You know what's crazy? Because PLD's damage mitigation scales with incoming damage, that means that a PLD now, in ilvl 70 gear available today, mitigates ~350 damage per second in the same example. That's how broken WAR is, a WAR in full endgame ilvl 90 mitigates according to your calculations ~300, a PLD in currently available ilvl 70 mitigates ~350. Oh, and that's passive mitigation, we haven't started talking about PLD's cooldowns yet!
