Isn't inner beast mostly a waste, as you're more than likely just going to waste heals as overhealing? If they converted it to a shield...We'd be in a much better place. Also baking in the +healing to defiance. Paladin's don't have to give up their defense buff to use their signature abilities, why should warriors?

Paladins are obviously going to be better at the moment, their mitigation ability favors worse gear. But better healer and better tank gear would get you more returns on the +healing from defiance.
