I would like this kind of rework but would ultimately like one last hung to be added.

An actual difference of game play between the stance.

Paladin somewhat has that with shield swipe (i'd reduce the CD to 5s max). That's one extra thing to do while tanking.

Something similar on the other job would be welcomed. I'm probably not the only one but, tanking has to be more than a dumbed down dps rotation with some ogcd placed to survive a specific attack.

Perhaps a more active Form of mitigation could be introduced via skills interacting with the tank stance to counter stronger AA from boss.
