It’s worth noting that Focused Will and Dispersion healing is essentially a PvP only ability, that DoT heals are getting nerfed by ~80% in Midnight, Halo heals are nerfed by 75% in Midnight, Void Shift is removed in Midnight, and Desperate Prayer requires wasting talents for shadow in Midnight.
Priest is statistically the least durable class in the game in PvE and it’s having its already terrible durability nerfed extremely heavily in the next expansion.
