Loving my Fire Mage, but have to try Ice Mage before I actually decide on anything =]
Ice Mages are pretty crazy with area of effect, but damage is slightly weaker. I find Fire Mage easier to combo with, and easier to juggle. Useful if you know how to utilize the juggle to push people out of the ring.
IGN: Chesters. I've lately been playing the Shadow Assasin, but I'm likely to switch around a bit (so long as the other ones don't expire :<). I haven't had much time to play though, and when I do, my screen mysteriously freezes/locks up and turns black after playing the game for ~15 minutes. I have to turn off the computer and back on to get back. ~_~;
