First came the complaints from non-Pally and non-Priest healers that Disc Priests were phenomenally overpowered in 5.2 (and really, for this entire expansion).
Then we saw Atonement nerfed by 20%, when they reduced atonement healing to 80% of damage dealt, down from 100%. Next came Ghostcrawler’s tweet that the reduction might only be a reduction to 90% instead of the 80% on PTR.
Well, Disc Priests can breathe a sigh of relief because Ghostcrawler’s tweet is a reality.
Atonement now heals for 90% of the damage dealt, up from 80%.
However, Disc should be aware that Glyph of Smite was nerfed to no longer transfer the additional damage to Atonement.
