1) Divine Aegis now works differently. It causes any critical heal to proc a bubble for 100% of the heal instead of doubling the heal. In other words, a crit for Holy is a 200% heal. A crit for Disc is a 100% heal + a 100% bubble. The bubble however benefits from mastery, so it's more likely a 100% heal + a 130% bubble.
2) Makes Prayer of Healing good for periods of restoring damage, but makes Power Word: Shield better for periods of preventing damage.
So on live, a critical heal with PoH will be a 200% heal + 100% divine aegis with mastery. Assuming a 20k normal heal and 30% mastery this means a critical PoH heal will be a 40k heal and 26k absorb for a total of 66k healing.
With this new ptr build and the same stats. A critical PoH heal will be 20k heal 26k absorb for a total of 46k healing.
Can anyone explain how a nerf to the healing component of PoH will make "Prayer of Healing good for periods of restoring damage?"
Edit: I just realised this is for all critical heals, not just PoH. So all of disc heals just got significantly worse, not just PoH. YAY!!!!!!!
