So far the top 4 things that come to mind that WAR will keep over DRK and PLD is as follows.

1. Storm's Path
-10% Damage Reduction
2. Storm's Eye
-10% Slash Resistance down that only NIN can apply.
3. Inner Beast
-20% Damage reduction almost on demand coupled with a strong attack and HP regen.
4. Steel Cyclone
-Really good AoE threat generator that costs no TP while PLD just has Flash and DRK's will cost MP.


WAR will still be the meat sponge tank that is only getting their DPS increased with the new DPS stance coupled with attacks, a fairly decent mitigation cool down and a strong self heal. If you don't have a NIN in the party, their slashing debuff will be important since I doubt DRK will be able to apply it.The damage reduction on Storm's Path is also pretty good too but might depend on what debuff they decide to give DRK on their third combo string. We also have to consider that the DPS output of all three tanks might be leveled out while in tank stance since PLD is getting a couple new attacks as well. Personally I feel that in terms of DPS while MTing it'll be WAR > DRK > PLD. It currently seems that DRK has to blow their MP pretty quickly to do more damage which will weaken them more then a WAR blowing their Wrath stacks to do Inner Beast for damage or Unchained.
