In DC universe online, things like Gap closers, cleaves and single target attacks designed to build higher enmity than normal ( similar to provoke I guess?) became standard for all tanks. This game should be that way too.

Maybe next expansion they'll add in cleaves. Probably change the name of warriors fell cleave into "Fell strike" since I don't think its a multi target attack at the moment. Or maybe "fail cleave" since they failed to cleave and instead put all the force onto a single enemy.
