It's all about Mage and Warlock..
I really think Frost and Fire is fun as Mage but they don't deal as good damage in dungeons as Arcane but Arcane is so dull for me. And then we have the Warlock, they are alot of fun but.. Doesn't Mage have more abilities that is like bom'bom'crazy'fuzzxplotions? Then Warlock's Destruction have? Help me out, share some of your opinions and I'll think a bit more about it and probably find my own, even tho I am level 70 with both and can't level any of them because I logout after 5 minutes just to go to the other character and back and forward like a crazy person! Blizz made them too alike!
