Another class tuning hotfix has been pushed to live servers which fixes the Affliction Warlock corruption bug, nerfing the damage output of the spec, especially on AOE.
Here was the hotfix that was applied this morning:
Corruption – Corrupts the target, causing (Corruption) (91% of Spell power) Shadow damage over 14 sec.
Flag Removed: Extra Initial Period
Previously, when any application of Corruption is refreshed, it caused an additional instant tick of Corruption as Xavian Teachings.
