I go mage, AoE spells etc in pretty much any RPG I play.
I just like casters, but I avoid healers like the plague because I can't stand using them. That an AoE mage is the only class I ever bothered to learn how to use properly (dam you WoW & DA:O !)
Theres something incredibly satisfying for me, sitting back and blowing my enemies up with power. Just thinking 'I'd like to see those guys overthere running around in flames' and then bang, they are.
Only problem? I can never carry enough plasters around to cover all those sword and axe related injuries I suffer...
