Agree with OP. I would hope that SE will focus on buffing PLD rather than trying to bring WAR down to its level. Ideally, PLD should be the overall "best" tank in terms of damage mitigation and enmity generation, while other tanks should specialize in specific encounters, perhaps having a slight edge over PLD depending on the specifics of the setup, but not overwhelmingly better in any situation. Other tanks should certainly not outperform PLD in most/all situations.
