If WoW was real, then there are no girls.
I'd choose priest. Same as RL. I like to heal people, carry away their stresses. But also, I'm a squishy, living in the proverbial mom's basement.
I'd never choose Druid, like the masses here. Transforming is cool, until a hunter searching for food mistakes you for a real bear, and shoots a Wyvern Sting at you to stun you, so you'd never had a chance to explain to him he was wrong. You then awake above a spitfire, still in bearform.
