Healers are a pain in the ass to kill. I’ve found that the power goggles + widow band help my 4 charge arcane blasts push it over the point where if I get two crits in a row they should die, assuming they didn’t start spam healing themselves while I was casting the first one.
It’s all situational and I’m glad I planned ahead for making a glass cannon set, because 9 times out of 10 I need the xtra int to get the job done
