paladin? Its dps rotation is the easiest out of the tanks. You have no stack mechanic, infuriate, triple fell cleave, decimate, raw intuition/vengeance for added stacks, or no storms eye/maim to worry about. Just 2 oGCDS, your dot, and mainly spamming your flashy as fuck dps combo right after your dot.
3 oGCDS if you are main tanking.
