In Season 4, we’re reducing the overall throughput of some healers to better align with our tuning goals. At the same time, we’re increasing the comparative power of Holy Paladin, Preservation Evoker, and Holy Priest without needing to further escalate the capabilities of healers.
The following adjustments are now deployed to the 10.2.6 PTR, and will go live with the beginning of Season 4 next week.
Monk
Mistweaver
All healing done reduced by 13%. Does not apply in PvP combat.
Druid
Restoration
All healing done reduced by 5%. Does not apply in PvP combat.
Shaman
Restoration
All healing done reduced by 5%. Does not apply in PvP combat.
Priest
Discipline
Developers’ notes: As part of our goal for balancing healers in raids, we would like to reduce raid healing output for Discipline Priest without affecting them in other content.
Atonement transfers 35% of damage to healing (was 40%).
Atonement healing increased by 70% outside of raids (was 50%).
Atonement healing increased by 35% in PvP (was 15%).
Monk
Mistweaver
Ancient Teachings healing transfer amount reduced to 375% in PvP combat (was 412%).
