For everyone saying tank utility is homogenized, consider that if a fight is designed to do a tank buster every 30 seconds and some of the tanks do not have a 25 second cooldown for it they may eventually run out of resources. WAR did not used to have utility or aoe mitigation and it put it at a disadvantage enough for Shake It Off's effect to be patched in.

Before someone thinks "if they need this homogenization because of raid design, then maybe the mitigation should function differently", TBN, Thrill of Battle, Nascent Flash and Sheltron all work differently and have different situations they excel at more than the others.
