I found a bug with the 4 pieces bonus of set of Destruction warlock, he should have chance to proc when you filled up a ember but he is proccing very random right now, I gain one proc from the very begining of the push without even casting conflagrate, immolate or incinerate, anyone has this issue??
I already reported on blizzard foruns but get no response so far.
I think if they correct this and using CR could be a improviment of Destro's DPS.
Sorry for my english, is not my main language and thankz for seeing this.
