Ah, now I see. And I agree with you 100%!
However, its not going anywhere because Yoshi P came out and (in a complete contradiction of your statement) said that DPS is part of WAR's utility, effectively giving them the most valuable utility there is. So really, when discussing nerfs for WAR, which may or may not ever happen, we have to consider the fact that the devs are unlikely to go back on that design. I feel like if anything PLD and DRK need some sort of raid DPS boost, albeit slight (nothing like Battle Litany or Trick Attack, save those things for actual DPS), if they're going to give WAR so much personal DPS, that way WAR is like the MNK of tanks, and DRK and PLD are like DRG and NIN.
Even that is unlikely though, cause then DPS would be part of DRK and PLD's utility as well, albiet raid DPS rather than personal DPS. This is really the only reason I've entertained the thought of defensive nerfs for WAR instead, very slight ones, that is, since I've been keeping in the back of my head all this time that WAR's DPS is probably here to stay, at least as an OT, and if DRK or PLD get any buffs to DPS they'll likely be raid DPS utilities, or narrowing the gap between their OT and MT DPS.
I wouldn't worry too much about this, as most of DRK's extra DPS is not in offensive cooldowns but in off-GCD weaving. They have 6x as many oGCD damaging abilities as WAR and 3x as much as PLD. One reason why I think tanks will never be "homogenized" is because DRK is so consistently fast-paced and active, and WAR is slow but heavy hitting, with PLD somewhere in the middle. Regardless of how they deal/take damage, they all have very different pacing.
Assuming you have very poor parry RNG and only get 3 Low Blows, DRK has-
2 Plunges (400)
3 Low Blows (300)
2 Reprisals (420)
1.5 Salted Earths (787.5)
1 Carve & Spit (450)
3 Dark Passengers (450)
...off GCD every minute. Every minute that's almost 2800 extra potency, 2400ish without Reprisals, off the global cooldown, while maintaining FoF-esque damage through Darkside and Blood Weapon being roughly equivalent to the DPS increase from Sword Oath, not to mention Blood Weapon's higher MP returns enabling you to push out 4 DA Souleaters per minute while keeping Scourge/Delirium up. And then all their potencies on their combos are higher as well. It'd take more than cutting the recast of FoF to bring them up to DRK DPS, but it'd at least make them competitive. In fact considering everything DRK and WAR have, now that I think of it, FoF not being on a 60s recast is straight-up kicking them when they're down, imo.
