Yeah, my mages are all arcane too. 3.2.2 is a huge buff for arcane mages, the liklihood of missile proc is going to be increased, and you can stack 4 arcane blasts, at a reduced mana cost for all, and when missile procs, it costs no mana. I was about to respec my mages Fire due to my warlocks leetness, but now I'm gonna just leave em arcane, and tweak the maro.
