A reaction based tank is and will always be worse than a passive tank. WAR needs at least some form of passive mitigation otherwise it will always be worse than PLD. Basing tank ability on the ability to heal damage taken is fine, but not when you start hitting content like Titan and Coil (assume you're not over geared) where stuff starts chunking your HP like no tomorrow. It's a needed change.

Inner Beast doesn't do squat if you're dead.
