Dps:
You enjoy yourself the most when you focus on a few tasks, and get really good at them. You love competing, you love winning, and you know you're really the best even if you don't. Your second love, or sometimes your first, is big numbers, dps in particular. Nothing gets your heart beating like a number going up.
Tank:
You work best alone, and like being in complete control (why overnuking is so frustrating to tanks). You live to tank the biggest baddest monsters in the world and come out ok. All the danger and exitement you want out of a fight is when something almost goes wrong, but you manage to fix it before anyone actually notice. Gear has little to do with vanity or competition for you, it's simply the only thing that stands between the raid and a giant ravenous monster, and you really want it to be enough.
Healer:
You play for the challenge, to stare wipe in the face and laugh. What makes you enjoy your job is the intensity, complexity, and the cooperation, which btw beats competition any day of the week. Since it's almost impossible to compete in healing, you don't spend too much thought on gear unless you really need it, though it's always a welcome help when you get something.
I'm definitely healer with a slab of tank.
