Does struggling with half-thought-through annoying ground-based mechanics with dumb CDs/cast times that some dev keeps shoving down mages' throats sound fun to you? Is being mildly useless whenever you have to move your piece of cake? Do you like having to work to down the world content others AFK through more efficiently? Pick mage.

Does playing the class with fluid rotation, excellent solo capabilities, capable of nailing every odd task that exists in modern raids appeal? Play Hunter.

TLDR: Mages = incompetent class designer nursing his pet 'brilliant' ideas. Hunters = WoW with cruise & climate control.
