Rampart being on the crossclass skills is honestly pretty weird. WAR now can have RI, Vengeance, Thrill, and Rampart as a part of their CD rotation - that's honestly a bit insane in terms of mitigation, not even counting Reprisal. I think the biggest problem is that this doesn't exactly equalize tanks that don't bring Rampart - WAR still has the same CD rotation it had before, but DRK/PLD are now missing a rather important part of their's.
