So once again Blizzard decides to change some not broken trait/talent/ability (comprounding horror) and leave bad/broken one unchanged (soul flame/wrath of consumption).Compounding Horror trait redesigned: its buff causes your next Unstable Affliction to deal (32% Spell Power) Shadow damage instantly, stacking up to 5 times.
And now we need to test it to determine is it slight buff or heavy nerf?
