Druid hands down, it is the ONLY class that can do all 4 roles. However, feral is one of the most complex melee specs in WoW, but you can streamline talents to make rotation easier. I have all classes at level 50 or higher that I stagger to keep updated as expansions come, even still, the Druid is my main since WotLK first launched, was a Hunter main before that. The class fantasy of Druid is just awesome and even though feral is complex, guardian is faceroll, moonkin is always solid caster dps and Resto is almost always S tier.
