I rerolled a priest. I am only level 12 right now but I am already getting massive amounts of kills with absolutely no downtime. And by this I mean, I haven't used a potion or drunk some water or eaten food since I was level three or four. Between this and my rogue, mage, hunter, and lock, this priest has been the easiest and most fun to level up. I would stronly advise for it for anyone.
