I started a mage last night and am having a blast. I specced as Frost, got the hang of the elemental, and went to town.
I entered a BG earlier and got called an idiot for playing as Frost. He said stuff like the elemental was worthless, despite the fact that I was popping rogues out of stealth left and right with it.
However, I did question whether I could be doing better with a different spec. At 21, I respecced and went Arcane. The tree at this level doesn't seem to be all that great. It just feels clunky. Arcane Blast is too slow, and Arcane Barrage + Fire Blast doesn't do enough damage for my tastes. I have yet to try Fire.
My question is, is there anything legitimately wrong with leveling as Frost right now?
