It seems that chaos wave benefitted greatly from the recent mastery buff, so i'm wondering when it's worth it to use your gul'dan charges for chaos wave instead of hand of gul'dan?
Tried it out on twins and didn't see much of a difference in either direction (using chaos wave x2 with cds when possible)
It's defo worth it on tectus it seems, but is there a rule to go by? i know that you're supposed to use it if the mobs don't live very long, but after the mastery buff it deals so much damage, i'm questioning whether it's worth it in every situation where you can buff it and hit multiple targets(2+) ?
