It's lies.

There is your clarification.

WAR was greatly buffed for phase 4 / release and PLD was slightly nerfed. This put both jobs on par.

A WAR can tank the same thing as a PLD and vice versa.

If there was a huge difference it will be rectified in a future patch.

WHM isn't better than SCH. DRG isn't better than MNK. BLM isn't better than SMN

The job is only as good as the player.
