Were you an AWESOME MAGE! But now you just suck?
Bad news, you just sucked, the truth is mages were on super easy mode.
While I don't agree with the shift from thm to con as healer. (partly because I leveled one to 40, then the other to 48, and not have to level the 40 if i want to heal)
I do think that SE needs to put full attention on the still horrid targeting system, but outside that, mages are where they should be balance wise.
