The PvP tuning has arrived to the 4 affected classes!

Player versus Player [with scheduled weekly maintenance]
Disintegrate damage increased by 33% in PvP combat (was 20%).
Developers’ notes: Devastation’s killing power outside of cooldowns is lower than we’d like, so we’re increasing Disintegrate damage further to help Devastation in PvP. In future patches, we would like to further expand on this effort and move damage out of Dragonrage and into other areas.
Penance healing is increased by 35% in PvP combat (was 15%).
Riptide healing is now increased by 25% in PvP Combat (was 10%).
Healing Stream Totem healing is now increased by 30% in PvP Combat (was 20%).
Unstable Affliction’s backlash damage increased by 35%.
