So, we can't untie the cool downs because they share a button.

Unchained is only useful when you know you either HAVE to stay in tank stance OR you are doing a berserk + unchained + overpower mega pull.

So why not just replace it? This would make them more self sustainable, maybe making up for their more complex rotation and less DPS? (I dunno, I don't actually parse)

This would make us a better Main Tank as healers could do more DPS instead of healing us. It would keep Enhanced Infuriate viable and not completely change our rotation (We would still be 3 / 4 inner beasts in berserk window without it and 6 inner beasts in berserk window with it just like Fell Cleave.)

This continued rotation is great in my eyes.
