Reasonable buff to war

[Shurrikhan]

Oh, and all three of these jobs make far more extensive use of aether than Warrior does.

Warrior literally raises dust storms around itself from emitted aether. That Warrior may use it less than the other tanks doesn't mean that Warrior would gain nothing of significance from their use of it. Nor should "use of aether" alone explain relatively poorer tank performance.

warrior only has shake it off, which costs resources.

No, it doesn't. It will still do 12% target HP absorption (greater than Divine Veil on co-tank, about even on melee, and only a bit worse on everyone else, atop affecting self while Divine Veil will not and stackable with ToB and TBN for 57% HP absorption) on a 25% shorter CD and without a healing activation requirement even if you feed it no resources. You also can feed it only the last 1 to .5 seconds of said buffs if you wish as their remaining duration does not matter at all. A well-used Nascent Flash provides more restoration than Intervention does mitigation except vs. one-shot mechanics and self-heals in the bargain. Both of those WAR tools are technically superior to PLD's. WAR just lacks Passage of Arms; that's it. As does GNB and DRK, who instead offer every 90 seconds nearly the same strength against raid damage as Passage of Arms does every 2 minutes despite the latter requiring no movement or actions over its use.

PLD offers the least free combined HPS/APS to its co-tank over time and its one additional raid mitigation skill is painfully situational. Aurora + HoS, TBN, and NF all outperform Intervention (the worst on-demand cross-mitigation skill) and Cover (a skill which deals no mitigation yet costs an Intervention or Shelltron).

When you're accustomed to privilege, equality feels like oppression.

Fair enough. However...

WAR hasn't really changed that much since Stormblood. If you're finding it boring now, then it almost certainly was boring then, too.

This... is badly erroneous or oversimplified, depending on how obtuse you intend to be. We might as well say that DRK without MP, lifesteal, Blood skills, or shadow aesthetics would still be just the same as when it had those things.

By all means, if you didn't enjoy the job before, don't feel compelled to give it even a fair shake now. But let's not call what was drastically changed for the less involved or entertaining for a significant number of players "unchanged".
