I've been wondering for a while how to get the most out of aoe and finally figured I would ask to see if anyone has some opinions on the matter.
I know it's usually rather controversial since it isn't usually simmed but its better to ask then not to ask.
I generally put nether tempest on 3 targets, put down flamestrike and then continue the single target rotation. The only other thing I do different is if the targets can be frozen I'll use all my freezes after I use frozen orb to get as many crits from it as possible.
If there's 5+ targets for most of the fight I simply swap to frost bomb and do the same rotation as above.
People have talked about using arcane explosion when there's a certain amount of targets as well. How many mobs are required before you would actually use it?
