I'm fine with PLD being the better main tank (their will always be a better one, if not PLD and WAR will just be the exact same job with different skin) but then, give us tool(s) to make us desired in 8 mans.
What I would really love is Steel Cyclone to be replaced with a DPS stance. I mean, come on, we're supposed to be the "DPS Tank" and yet it's PLD who gets the DPS stance AND the best DPS buff out of the two jobs.

Just delete Steel Cyclone and give us a stance that give us different Wraths stacks. Like +3% damage and 20% of our parry swap with strenght/crit/determination (pick one ), stackable 5 times for a total of +15% damage and 100% of our parry swaped with a DPS stat, and a permanant -50% on enmity generated.
Those are random numbers. What I would like is something like, with equal gear and equal skill, a WAR in DPS stance would deal between 10 et 20% less damage than a DRG/MNK (again, random number, just need the right number to not be OP).

That would make us a better option than a SECOND PLD in 8 mans while staying a different tank, and a propper WAR. When you need just one tank, you're a decent DPS that can still use self heal and has a great health pool to relieve pressure on the healer but it can be swap whenever it is needed to Defiance to become that Off Tank that the WAR seems to be ATM.
