I love the idea of dancer, and I'd totally main the crap out of that. But at the same time, it kind of makes me laugh hysterically.
As a healer: "Hmm, you seem to be missing some HP. Let me dance seductively for you so you can regain it." "You seem to be missing a lot of HP, better break out some krumping."
As a DPS: "Let me just shimmy my body to make you hurt."
