Personally, I'm of the opinion that mitigation for tanks don't need to be, or even feel, different. It's the other portions of their kit that should change how they feel. Mitigation should be straight forward and effective. I already take issue eith the tanks third mitigation being awful for trying to be unique. Dark Mind is only situationally useful and WAR's mitigation shares a recast timer with Nascent Flash on top of its super low duration.

I'd rather the mitigation tools be useful and effective across all tanks than devs screw them up for the sake of feeling unique.
