I've always been partial to melee, so Ninja (of the Tactics variety, not XI). Like someone else said, though, I don't care what weapon I'm using, be it fists, knives, axes, or what-have-you; as long as can run up and beat the crap out of my enemy, I'm happy.

Though, I do also like tanking, so maybe I would've taken an XI-style Ninja, too. . .
