Parry: How would you improve it?

[ashwich]

I'd remove it. It'll always either be too weak to help with mitigation so you ignore it, or so strong that every tank HAS to maximise it which isn't any more interesting than going for DPS now.

There will ALWAYS be a stats that every tank maximize. if this is the fact that isn't interesting, there're some major stats overhaul that needs to be done.

The difference is you stack them for a different reason. After a raid night you come back and look at logs and go "look at all the damage I prevented through mitigation" much in the same sense that dps look at how much damage they dealt. It's a kind of satisfaction that your unique role brings. now this doesn't exist. I for one don't feel nearly as accomplished comparing dps to other tanks, it's not even my job.
