Numerical adjustments definitely need to be made. And honestly, neither myself nor anyone else has any real reason to be skeptical of Squenix's ability to make this balance work, given the glorious (in my opinion) way that they balanced DPS and Healing jobs over the course of the transition to 3.0 and the months that followed, to say nothing of bringing DRG from the most maligned job in the game and butt of countless jokes to the staple of raid groups that it is now. There's not a single DPS or healer job that I wouldn't seriously consider bringing to my raid group, provided an over-all party balance is still struck (no 3 caster 1 melee-type shenanigans). The tank design and performance data in content right now is grossly skewed as we all know and I'm frankly shocked that they've done so little about it and that it wasn't addressed alongside the fixes to AST/MCH and the minor buff to DRK. The state PLD is in compared to the state WAR is in, is a straight-up stain on the dev team's talent for designing jobs. The fact that people are even discussing bringing a second WAR to their raid group in a meta where WAR+DRK has tremendous synergy is saddening, almost as saddening as the almost-completely unexplored synergy of a DRK+PLD group.
My biggest worry with PLD is (and I've outlined this in other threads), the fact that Squenix picked up the shovel and glued it to their hands with these all-but-useless defensive utilities that serve next-to-no purpose in end-game content, or serve their purpose for a relatively minimal amount of uptime, or are just cumbersome to use for a tank. If PLD's DPS and/or enmity is buffed it still won't change the fact that their raid utilities are ham-handed at best, and the offensive combo finishers they received are pure damage and offer no utility, making them the only tank to have their solo combo-based utility tied to their enmity combo, which also happens to be their weakest combo. If they nerfed WAR, they would not have to nerf it nearly as hard as they would have to buff PLD. I absolutely want every tank to be able to succeed in content, but it just feels like in order for the job to "feel" as good as WAR and DRK do, they would have to do SO... MUCH... that it almost seems like they would HAVE to nerf WAR ever-so-slightly to keep them from having to completely etch-n-sketch PLD's design.
But at the end of the day, you're pretty much 100% right.
