Yeah, the math just adds as such that the PLD's innate 20% mitigation (well, not innate, it's Shield Oath) gives them the upper hand. It has been discussed in several other of these forum threads. People are calling for a fix, as there is nothing that a Warrior is apparently needed for currently. I'm not at end-game yet, so I can't say personally, but the over-all consensus is that Warriors are second class citizens in all raiding or big-target events. At least according to public opinion.

They look way sweeter though. After I get PLD up to 50 and get some reasonable gear I will be leveling a WAR to check it out.
