Blizzard is giving a power increase to certain classes with the next WoW: Dragonflight weekly reset. When servers reset on April 11, three Healing specs, two DPS specs, and one tank are being buffed in PvE content.
The most notable changes in the upcoming reset are being doled out to Priests, as Discipline will have its healing throughput increased, while Holy Priests will have their damage output upped. Discipline Priests in particular will see a massive boost to their numbers, with the shield strength of Power Word: Shield being increased, as well as the mana costs of PWS, Renew, and Power Word: Radiance all being decreased. These changes should relieve some of the pressure that Discipline Priests have felt during lengthy, demanding encounters, particularly in Mythic+ dungeons.
