Be warned if you have any mistweaver monks in your raid when you work on Primordius. One of the mechanics is you get good buffs but if any mistweave monks pop revival for a healing cooldown, its AOE dispel mechanism removes the good buffs along with any bad buffs, which obviously is not good for this fight.
This has happened since PTR, which brought about much discussion for bringing a monk glyph which would remove the dispelling part of revival, but nothing went live, nor does it seem that they have fixed Primordius to allow the use of revival without it removing good buffs.
The March 7th hotfixes included:
The Mistweaver ability Revival will no longer dispel players who have any of the following effects:
Primordius: Clear Mind, Fully Mutated, Improved Synapses, and Thick Bones
Durumu: Dark Parasite
Jin’rokh the Breaker: Ionization
All the monks can breath a sigh of relief 🙂
