Enough is enough

You are completely incorrect, first no PLD in Sword Oath was out DPSing a WAR OT unless the WAR just wasn't good, and we're talking BiS left side and full crafted/melded accessories. On pre-echo Twintania WAR OT could get very close to a mid tier DPS I still ended up going MNK instead of WAR when we switched to single tank for Dragon Kick and MNK was the highest DPS at the time.

I feel bad groups if they had WAR MTs in brand new content, i.e. less than optimal gear levels. PLD is more forgiving so if you don't know the mechanics well you can still clear while WAR requires a perfect cool down rotation because Inner Beast is on the global and buff delay. If you're even a second off on getting it up it won't effect the incoming tank buster. Pretty much if Inner Beast isn't up before the cast gets to half then it won't effect the damage. Also that "fluff" damage is pretty detrimental in new content since your healers are also under-geared so any means of reducing that is welcomed. Plenty of top tier groups had their PLDs meld DEX into fending accessories for even more "fluff" mitigation when they were pushing world firsts.

I challenge you to show concrete proof of a world first clear that used a WAR MT, pre-Heavensward. Even the first 5 clears will have PLD MT.

On top of PLDs dominating the MT slot in world firsts, there were also very few fights that actually required two tanks, and PLD was the optimal choice for a single tank since they have far more "Oh S@#$!" buttons.
