Holy and Disc Priest Healing from Alpha Warlords of Draenor Patch Notes

discpriest

Healing priests are seeing many changes in the Warlords of Draenor alpha patch notes.

First, Disc Priests will certainly to be disappointed to know – however, not likely to be surprised – that Atonement is getting nerfed.  Blizzard admits that he grew out of control during Mists of Pandaria, and it wasn’t unusual to see Disc Priests doing nothing but Smiting with some Power Word: Shields thrown in for good measure.

Atonement healing has been reduced by 25%.  However, Smite has been buffed by 20%.  What does this mean overall for Atonement?  Fortunately, Twintop (@TwintopTahoe) has already done the math for us at H2P.

Smite does 100 dmg now. Atonement does 90 healing.

The atonement change, 25% less, means Atonement (should) now do 67.5% of the dmg done as healing.

If Smite is buffed by 20%, then our Smite cast now does 120 dmg, and 120 * 0.675 = 81 healing.

So it is a net nerf.

Disc Priests have also become overpowered with their level 90 tier talents – Cascade, Divine Star and Halo.  When Blizzard removed AOE cap from the spells in that particular tier, Priests completely dominated healing meters for the majority of fights, due to the way the overhealing interacted with Divine Aegis, which meant the raid was being shielded with huge absorbs.  This left other healers with little to heal, while waiting for the damage to burn through the huge Disc Priest absorbs first.  Blizzard has returned AOE capping to Halo and Divine Star.

We are also seeing some changes with Chakras, because they were concerned about it being a penalty for being in the wrong Chakra, as opposed to the planned bonus of being in the correct one.

Chakra: Serenity now increases healing of single-target spells by 10% (down from 25%).
Holy Word: Serenity now heals for 40% more than before.
Chakra: Sanctuary now increases healing of area-of-effect spells by 10% (down from 25%).
Holy Word: Sanctuary now heals for 60% more than before.
Rapid Renewal no longer reduces the global cooldown of Renew.

Prayer of Mending is undergoing a change which many priests are to be pretty happy about. Prayer of Mending has the stipulation that “This spell can only be placed on one target at a time.”  It wasn’t unusual for Prayer of Mending wars to break out, especially for those looking to rank on fights.  Multiple priests can have Prayer of Mending on the same target now.

Holy Nova has been made a Disc Priest only spell, and will no longer require a glyph.  Healing from it has been increased, to provide Disco Priests with an AOE heal.

Many instant cast heals have been given a 1.5 second cast time, which includes the 90 tier talents.

Prayer of Mending now has a 1.5-second cast time (up from instant cast).
Cascade now has a 1.5-second cast time (up from instant cast).
Divine Star now has a 1.5-second cast time (up from instant cast).
Halo now has a 1.5-second cast time (up from instant cast).

Heal has been removed.  But they have made their differences between what they see as mana efficient versus mana intensive with a higher throughput.

Priest Higher Efficiency: Greater Heal, Circle of Healing, Prayer of Mending, Holy Nova (new Discipline-only version), Penance

Priest Higher Throughput: Flash Heal, Prayer of Healing

There is also a significant amount of abilities being pruned from Priests (and from all classes).

Binding Heal is no longer available to Shadow Priests.
Hymn of Hope has been removed.
Heal has been removed.
Greater Heal has been renamed Heal.
Inner Focus no longer provides any mana cost reduction.
Rapture has been removed.
Renew is now available only to Holy Priests
Shadow Word: Death is now available only to Shadow Priests.
Void Shift has been removed.
Inner Fire has been removed.
Inner Will has been removed.

The Hymn of Hope removal (and the nerf to Mana Tide Totem) will be felt from healers relying on those mana sources for mana regen.  Blizzard felt too many healers were reforging out of too much spirit while relying on outside mana sources.  However, this will definitely be felt in WoD when every last mana point counts.

For Disc Priests, their power has always been in their ability to create those huge absorbs. What does this mean for disc priests going into WoD? Blizzard is planning to have less first healing, and they don’t expect the raid to be at 100% health the majority of the time.  But whatever there is any kind of damage going out, disc priests nearly always will perform well – although at the start of Mists of Pandaria, Disc Priests were fairly weak compared to other healing classes.

On the positive side, Priests have the ability to change healing specs between Disc and Holy depending on which spec is looking the best once we hit the first tier of raiding in WoD – other healing classes don’t have that luxury, as it will require leveling another healing class to 100, if their preferred healing class isn’t performing well.   And healing Priests often found themselves having to switch specs this expansion since some fights heavily favored Holy while others heavily favored Disc.

We will have more Disc and Holy Priest notes as we continue to watch blue tweets.

Lots of new healer changes announced for Warlords of Draenor

Healers finally got a nice big Dev Watercooler today and had a great deal of information tp finetooth comb over about the upcoming expansion and how it will affect healers in Warlords of Draenor.

First, we also have posts on the individual classes if you want more specifics where I am adding all the class specific tweets the Blues are making today, so definitely check them out for even more detail…. Resto Druid, Resto Shaman, Holy Pally, Holy & Disc Priest, and Mistweaver Monk

Rethinking Health Bars

Blizzard doesn’t really like how the healing game has changed from thinking about every heal and every individual player’s health pool, to the current “spam them as fast as you can to heal them to 100%” with *absorb* *smartheal* *absorb* that is happening now.  And this is actually the reason why we saw a lot more bursty damage this tier than in previous tiers, because bursty damage was the only way to challenge healers – and really, that’s not a challenge, its all about who has the fastest trigger finger and the most haste after the mass absorbs fall off.

One of our goals for healing in Warlords of Draenor is to tone down the raw throughput of healers relative to the size of player health pools. Currently, as healers and their allies acquire better and better gear, the percentage of a player’s health that any given heal restores increases significantly. As a result, healers are able to refill health bars so fast that we have to make damage more and more “bursty” in order to challenge them. Ideally, we want players to spend some time below full health without having healers feel like the players they’re responsible for are in danger of dying at any moment. We also think that healer gameplay would be more varied, interesting, and skillful if your allies spent more time between 0% and 100%, rather than just getting damaged quickly to low health, forcing the healer to then scramble to get them back to 100% as quickly as possible.

Watcher also tweeted the same sentiment about how it isn’t an ideal situation.

When healers can top off critically injured players in seconds, encounters have to try to kill players before healers can react. Not ideal.

Blizzard wants to see things back to the time where the raid wasn’t at 100% health, but you didn’t have the “OMG he/she is going to DIE!!!!” you sometimes get now.

To that end, we’re buffing heals less than we’re increasing creature damage. Heals will be deliberately less potent compared to health pools than before the item squish. Additionally, as gear improves, the scaling rates of health and healing will now be very similar, so the relative power of any given healing spell shouldn’t climb so much over the course of this expansion. For those concerned about what this means for raiding, don’t worry—we’re taking all of these changes into account when designing Raid content for Warlords of Draenor.

This will be nice and make healing a lot more challenging to healers over the course of an entire expac, rather than generally getting less challenging overall (raid mechanics aside) when healing.

Percentage of Health Spells

Blizzard is making changes to many spells based off percentage of health, although they say the changes are actually in line with the changes to other healing spells.  They haven’t gone into specifics yet, but hopefully we will know more soon.

Added: Gift of the Naaru is one that will be changing.  It is currently “Heals the target for 20% of the caster’s total health over 15 sec.”.  Will now be “Gift of the Naaru heals for 4% of your max HP, every 1sec, for 5sec.”

Many Instant Casts now have a 1.5 second cast time

Many, many instant cast heals have gotten reworked with a significant 1.5 second cast time.  Blizzard felt the mechanic of running and healing at the same time removed some of the complexity and decision making behind healing.   For instant casts, all of the following have been hit with a 1.5 second cast time: Druid’s Wild Growth; Monk’s Uplift; Paladin’s Eternal Flame, Word of Glory and Light of Dawn; Priest’s Cascade, Divine Star, Halo, and Prayer of Mending.  Shaman’s did not have their one instant cast (Riptide) reworked with the cast time.

The loss of insta-cast heals will be pretty significant from a “OMG, save the tank!” moments when all the healers decided to target someone else in those crucial seconds or if the tank missed a cooldown and the other tank forgot to taunt and you need to attempt to keep him up.

Right now, these are the only instant-cast heals being affected by the new 1.5 second cast time, so you can breathe a sigh of relief over anything left.

Yes. The only currently planned changed to cast times are the ones listed in the blog.

That said, Nethaera says (in comment on the watercooler) they are planning raid encounters in WoD to take into account these changes.

We’re also taking a look at Raid design as a larger part of all of these changes. So, rather than having to make encounters that do a lot of damage to counter the large health pools and player healing ability, we can pace the damage in these encounters a bit better and allow healers to make better healing choices as a part of the gameplay.

However that won’t really help save people who stand in bad for a tick too long or don’t use personals.  And a bitter part of me suspects PVP also had a role in this change, since these are now interruptible.

Mana in WoD

They are planning to focus on making healers be but much aware of their mana and their subsequent healing decisions based on it.   However, there are changes to spirit and baseline regen according to Watcher.

Baseline regen will be higher, Spirit will still be good where you can get it.

But they did make one nice change – healers are so used to sucking mana dry at the start of an expansion, but they are making it easier for healers this time around.

All of this discussion of efficiency may cause most healers to start worrying about mana regeneration and their mana pool. To allay those concerns, we’ve increased base mana regen a great deal at early gear levels, while having it scale up less at later gear levels. This will make all of these changes play well even in early content such as Heroic Dungeons and the first tier of Raid content, and also play well in the final Raid tier without mana and efficiency becoming irrelevant due to extremely high regeneration values.

For some healers, it has almost become a game to see how low they can get their spirit (and then cry for Mana Tides).

Speaking of Mana Tide, Blizzard has not said anything about MTT, so it is unclear if it will be reworked yet again.  I do miss the Cataclysm days when it became an art to drop Mana Tide when your Tsunami Darkmoon Card Trinket proc’d, I would love to see there be some wiggle room again by allowing spirit proc trinkets work with Mana Tide, even if other tricks don’t work.

Baseline spirit is going to be higher, which is important since healers won’t be getting as many gear pieces with spirit, which is a definite turnaround from the usual “every piece has spirit unless you specifically choose a non-spirit one”.  Celestalon stresses that gear will not matter less to healers because of the change, although many guilds tend to gear DPS first to meet early DPS checks in early expansions.

Low Cost Spammable Heals Gone

Blizzard has given the axe to many heals they saw as being both “low-throughput, low-mana-cost heals” – basically the healing spells healers do when everyone is topped off, there is no imminent incoming damage, and you want to maybe spam heal the tanks without wasting mana if it is an overheal.

While it seems they haven’t included all the heals, they have listed several kinds as being removed including Nourish, Holy Light, Heal, and Healing Wave.  They are reusing some of these names with the less mana efficient big brother of the heals, such as Greater Healing Wave being renamed Healing Wave (yes, I can see this causing all kinds of confusion when it goes live).

I can see why Blizzard did this, as they want to make healers think about every heal they make, and lose some of the “afk spam” type heals we all do at some time or another.  The comparison was made that these low cost heals end up as being like an auto-attack for healers, which is probably a fair comparison.

However, how does this affect the “always be casting” mentality and the goal to have 100% uptime – even if healers feel this isn’t ideal, many raid leaders who don’t know much about healing will cite “But your uptime was only 82% according to logs!  FIX IT!!”  Perhaps that 18% was everyone topped off and it was a non-absorb class.  And by the same accord, healers don’t generally like fights where they sit around twiddling their thumbs with nothing to heal either.

Low throughput heals served a role of feeling like the auto attack for healers. Do healers frequently do nothing during combat?
Your efficient single-target heal (Healing Wave, Holy Light, etc.) should still be a mainstay. Unrelated: Big fan of Healer:ALitD (WatcherDev)

Having a heal you can always be casting without worrying about the mana cost seems important to prevent healers just watching.
Agreed, I see the value there. For some, a DPS filler can work fine (free Lightning Bolt for shaman, Atonement for Disc, etc.). (WatcherDev)

Which heals for which jobs

Along with the changes to the low-mana low-efficiency heals, they are also prioritizing which heals they feel healers should be using depending on the situation:

Druid Higher Efficiency: Healing Touch, Rejuvenation, Efflorescence
Druid Higher Throughput: Regrowth, Wild Growth

Monk Higher Efficiency: Soothing Mist, Renewing Mist
Monk Higher Throughput: Surging Mist, Spinning Crane Kick

Paladin Higher Efficiency: Holy Light, Holy Shock, Word of Glory, Light of Dawn
Paladin Higher Throughput: Flash of Light, Holy Radiance

Priest Higher Efficiency: Greater Heal, Circle of Healing, Prayer of Mending, Holy Nova (new Discipline-only version), Penance
Priest Higher Throughput: Flash Heal, Prayer of Healing

Shaman Higher Efficiency: Healing Wave, Riptide, Healing Rain
Shaman Higher Throughput: Healing Surge, Chain Heal

Watcher has also said that it will be your efficient single target heals that will be a big part of your healing toolkit.

Your efficient single-target heal (Healing Wave, Holy Light, etc.) should still be a mainstay.

Along with this, they want to stress that healers should be in the business of decision making which heals to use, rather than just using your go-to heal as many do currently.

The goal isn’t to make healing harder, actually. I’d say it’s to replace testing reaction time with testing decision-making.

Passive and Smart Heals

There has been a lot of backlash against passive and smart heals this time.  We had two trinkets this time around that did some form of smart healing (Cleave and Multistrike), heals have become “smarter” and it means a lot less healing is left to be done by true targeted healing.

We also took a look at healing spells that were passive or auto-targeted (so-called “smart” heals).

We want healers to care about who they’re targeting and which heals they’re using, because that makes healer gameplay more interactive and fun. To that end, we’re reducing the healing of many passive and auto-targeted heals, and making smart heals a little less smart. Smart heals will now randomly pick any injured target within range instead of always picking the most injured target. Priority will still be given to players over pets, of course.

On one hand while this will bring some cheers, it will also be jeers with the mechanics.  Remember some of the “dumb heals” we got from trinkets/weapons in previous expansions where we would see a trinket heal go and heal someone missing 2 health points and bypassing the tank who was about to die?  It became a contest of sorts after every boss to see whose trinkets actually did real healing instead of overhealing.

I’d almost rather see it go to the most injured player within a closer distance (ie. heals the most injured player within 20y instead of 40y) but then I could also see that cause a huge issue with Mistweavers rocking those heals because range healers had to be 30-40y out because of some boss mechanic.

So I am not sure what the real solution is, since smart heals have been so dominant, but I can see a lot more overhealing.

Celastalon has also confirmed that all smart heals will be changing.

It’s safe to say that we’re changing all smart heals.

Blizzard also likes the idea that “smart heals” will turn into “not-so-smart” heals, making them random and unpredictable.

That’s the point. It also emphasizes single target heals in supplement.

We are also going to see the 6 player cap on “smart heals” for performance issues.

Probably will have a target cap of 6 for better client/server performance. Will hit 6 random injured players.

Absorbs

Ah, absorbs, the bane of every healer’s existence but Discs and Holy Pallies.  While it wasn’t such a headache for non-absorb healers earlier this expac, this tier has been pretty painful.  Blizzard had previously said they were going to make some changes to absorbs, but while they once again acknowledge the problem, they haven’t really said specifics, other than they will stay true to Disc being an absorb class.

Additionally, we’re toning down the power of absorbs in general. When they get too strong, absorption effects are often used in place of direct healing instead of as a way to supplement it. We will, of course, take these changes into account when tuning specializations that rely heavily on absorbs, such as Discipline Priests.

But with the changes to the health pool, where Blizzard doesn’t necessarily want everyone at 100% nor healers have the ability to just easily top the entire raid off quickly and efficiently, absorbs will have a lot less of an impact to overall healing numbers, and could make them quite poor on some fights (think of a fight like Valithria Dreamwalker, Tsuong or Chimaeron where raw HPS output is needed)

Single versus Multi-Target

Blizzard wants to make healers have to think about what kind of heal they want to use, a single target or multi-target heal.   As such, they are reducing the mana efficiency for many multi-target heals.

Another of our goals for healing in this expansion is to strike a better balance between single-target and multi-target healing spells. We’ve taken a close look at the mana efficiency of our multi-target heals, and in many cases, we’re reducing their efficiency, usually by reducing the amount they heal. Sometimes, but more rarely, raising their mana cost was a better decision. We want players to use multi-target heals, but they should only be better than their single-target equivalents when they heal more than two players without any overhealing. This way, players will face an interesting choice between whether to use a single-target heal or a multi-target heal based on the situation.

There is no word on how this change will affect Shamans, whose toolkit is really geared towards multi-target healing with Chain Heal and Healing Rain, and it really is their niche.

Back to Cataclysm?

The changes seem to be another throwback to Cataclysm, and I am not the only one who sees that and is concerned about it for the health of healing overall (no pun intended!), but Watcher had a bit of reassurance for those with bad memories of the start of the first Cataclysm raiding tier.

Cata’s healing had upsides and downsides. We’re capturing the upsides, and preventing the downsides.

But Cataclysm also brought a fair amount of healing issues with healing being so difficult and painful that a lot of healers switched to tank or DPS instead.  And don’t even mention the abuse we endured back them while trying to heal a some of those dugeons, like heroic Grim Batol – if you got past the first boss, you were #winning.

It may give exceptional healers more room to distinguish themselves. But we plan to avoid the pitfalls of early Cata healing.

Fortunately, Blizzard does acknowledge that mana regen was a serious issue in early Cataclysm days.  I remember farming non-stop for the Darkmoon Card: Tsunami trinket and the Archaeology trinket Tyrande’s Favorite Doll just so I had a tiny bit more mana and mana regen for bosses because going OOM was such a real issue.  And yes, it would be really awesome to have another version of Tyrande’s Favorite Doll for WoD, so those who are really suffering (or want to be super awesome) can farm it.  It was a real shame that the Archaeology items this expac were only blue quality and not epics, and no decent healing item.

Mana regen was a huge issue early Cata, along with overtuning. Created a trap for many healers; too easy to OOM.

Final thoughts

Fortunately, Blizzard says they will keep a close eye on how testing goes with the changes (speaking of which, hopefully we get beta soon, especially since we will have to do the 90-100 grind to get true level 100 testing in for healing).

The developers plan to keep a close eye on how testing goes in the beta with all of these changes. It’s a lot of interconnected systems changes so there’s a lot to take into account. Hopefully, with some great focused (and constructive) feedback, they’ll be able to continue making solid decisions to get the results they (and the community) are looking for. (Nethaera)

And don’t forget this is just a slice of the current changes – I have many things in my mind I think would be pretty awesome if they changed for healers, so my fingers are crossed that some of them could possibly happen.

What do you think?  And don’t forget the indivudual class posts which have more class-specific info from the Dev Watercooler and all the zillions of tweets the blues are doing today: Resto Druid, Resto Shaman, Holy Pally, Holy & Disc Priest, and Mistweaver Monk

Happy healing :)

Upcoming Disc & Holy Priest Changes in Warlords of Draenor

The new healer water cooler came out today with some great information.

Priests are losing many instant cast heals they currently have.  Cascade, Divine Star & Halo now all have 1.5 second cast times.  Prayer of Mending is now 1.5 second cast time.

Heal is being removed (although the name could be reused later).

Divine Star will be nerfed (sorry Priests!)

Divine Star is probably the most overpowered spell in the game, currently. It will be nerfed in 6.0.

They have also broken down what they see as higher efficiency heals vs higher throughput (but more mana expensive) heals:

Priest Higher Efficiency: Greater Heal, Circle of Healing, Prayer of Mending, Holy Nova (new Discipline-only version), Penance
Priest Higher Throughput: Flash Heal, Prayer of Healing

They plan to dampen down the amount of absorbs in the game, but say they will still be conscious of the fact that Disc relies on absorbs for its healing spec.

Additionally, we’re toning down the power of absorbs in general. When they get too strong, absorption effects are often used in place of direct healing instead of as a way to supplement it. We will, of course, take these changes into account when tuning specializations that rely heavily on absorbs, such as Discipline Priests.

There are some Atonement changes as well, according to Celestalon.

Atonement will not be as much healing throughput as normal healing. Does significant damage when you don’t need as much healing.

 

 

No plans to remove the dispelling CD

Remember the days (oh how we loved you Heroic Sinestra and Heroic Spine of Deathwing) when healers could lovingly dispel their fellow raiders every global?  And the much beloved Cleansing Totem?  Ever since Blizzard made the change to put a cooldown on dispelling, there have been cries from healers to remove it.  While a CD makes sense for PVP, when it comes to PVE, you sometimes have to plan comp around which healers you have to dispel (cough, Horridon).  Well, Blizzard has officially said there are no plans to remove the dispel cooldown in Warlords of Draenor :(

What do you think about removing the cooldown on dispel in the near future?
Holinka: We don’t plan to remove it. (Source)

Sorry to crush all your hopeful dispelling dreams for Warlords.

Where Holy Priest Mastery is going for Warlords of Draenor

Mastery hasn’t been a very strong stat for holy priests, particularly when there is a lot of overhealing going on (which there usually is, unless a guild is deliberately underhealing a boss).  Blizzard answered some questions about the role of mastery for priests and if it is being reworked for WoD.

Any chance on HPriest mastery being relooked at for WoD? Maybe turn all the overheals from it into something?
Echo of Light us something we balance assuming it’s going to be more overheal than average. More of regen than healing in design. (Source)

It’s not really a choice when it maths out to be 25% or less of the value of other secondaries in typical 25H.
That only sounds accurate when significantly overhealing, and only if your goal is topping the healing meters. (Source)
If you’re not overhealing, and your goal is minimizing deaths, mastery can work well. (Source)

And when in the last 3 expacs has there not been significant overhealing most of the time even progression?
I’m referring to using more healers than you need. Doing so results in RShams looking weak, and Discs strong. (Source)

Sounds as though it will be another one of those things that will work well earlier in the upcoming expansion, similar to how priests were stronger at the start of this expansion too.

Disc Priest bug fixed with Power Word: Barrier

power word barrier 600If you noticed something weird with how Power Word: Barrier was affecting targets under it, and people getting interupted when it was placed, it is a bug that has now been hotfixed.

  • Resolved an issue that caused Power Word: Barrier’s damage reduction effect to not apply properly to players under various conditions.

Hopefully it didn’t hurt too many people working on progression.

New Priest Talents for Level 100 in Warlords of Draenor

We have the new talents that were on preview today for the new expansion Warlords of Draenor.  Here are the Priest talents (I am including Shadow talents for reference as well):

First Talent Choice – Power of the Void

Discipline & Holy
Shifting Perspectives
Passive
Your Void Shift spell has no cooldown, but can only be cast on allies with less health than you, and no longer heals.

Shadow
Void Enropy
All Shadow Orbs – 40 yd range
1.5 sec cast
Consumes up to 3 Shadow Orbs to deal up to 750 Shadow damage every 3.00 sec for 60 sec.

Second Talent Choice – Divine Clarity

Discipline
Clarity of Will
1,000 Mana – 40 yd range
2.5 sec cast
Shields the target with a protective ward, absorbing 2500 damage within 30 sec.  Replaces Greater Heal

Holy
Clarity of Purpose
1,000 Mana – 40 yd range
2.50 sec cast
Heals allies within 10 yards of the target for 5000, split such that more injured targets will receive a larger portion of the healing.  Replaces Greater Heal.

Shadow
Clarity of Power

Disc Priest Spirit Shell being reduced from 15 seconds to 10 seconds

A significant nerf for Disc Priests with Spirit Shell now only active for 10 seconds on a target, down from 15 seconds.  This change is seen to affect 25M raiders more than 10M raiders, because of the differences in how Discs use Spirit Shell under those circumstances.

Pre-5.4, Spirit Shell: For the next 15 sec, your Heal, Flash Heal, Greater
Heal, and Prayer of Healing no longer heal but instead create absorption
shields that last 15 sec.

5.4 PTR: For the next 10 sec, your Heal, Flash Heal, Greater
Heal, and Prayer of Healing no longer heal but instead create absorption
shields that last 15 sec.

Of course, this is PTR, and things could change.

Disc Priest Rapture changed for mana gains

A new change has hit the PTR for Disc Priests, although how it will really affect Disc Priest’s mana remains to be seen – people are conflicted about whether it is a gain or a loss at this time.

The change:  Rapture now energizes the Priest for 100% of the mana cost of Power
Word: Shield When the shield is fully consumed or is dispelled (used to
energize the Priest with mana equal to 150% of their spirit). This is
the modified mana cost for Power Word: Shield, after being reduced by
Rapture’s passive effect.

There is currently discussion as to how this will really affect mana for Disc Priests at HowtoPriest
