I have both. I always was main with WAR. But its not like the mythology is going to be such a huge importance since i80 gear will be available.

The big difference is that PLD can MT everything in the game. WAR cannot with the same level of ease (if at all but for the very rare group). After the patch, PLD can STILL TANK all the content just like they did before. But WAR's should be able to do just the same, perhaps better, perhaps not.

A PLD getting mad about the changes is crazy. They are taking nothing away. Only putting the other tanking class on par (or better). If your worried about your tanking spot in coil... then you should be more worried about the company you keep and ability to play instead of a buff to another class.
