Balance druids do well. They're a great hybrid that can throw down huge burst dps, and toss out decent heals if need be as well. They are very mobile due to travelform, roots, dash, and moonfire spam, and can escape from sticky situations with ease. They also have the adavntage of picking and choosing (most) of their fights because they can start out stealthed in cat form.
In balanced gear you can throw out 1200+ starfire crits, or machine gun 300-700 wraths on top of your 2 dots that do decent damage in and of themselves.
