What if we designed other Tank's abilities like they were made for WAR?

[Launched]

PLD gets Veil which provides a shield and a heal.
WAR gets a Shield, a Heal, a Regen, and it also has a bonus damage boosting mechanic, and of course both the healing on Shake and the shield from shake are larger than Veils.

Tank that literally brings a shield to a fight is less sturdy than the tank with a big axe.

PLD has an entire extra raidwide mitigation skill in Passage of Arms.
Shake it Off doesn't boost damage. Its shield is based on each party member's HP, unlike Divine Veil, so it gives roughly the same size shield on DPS/healers unless you consume multiple cooldowns.

Or how about short mits,
The other tanks have to choose between defending an ally or themselves with their short mit. TBN,HoC,Intervention all only affect your target.

PLD can save enough gauge to use Holy Sheltron and Intervention at the same time. TBN has the shortest cooldown, and DRK also has 2 charges of Oblation.
Dark Mind has a 60 second cooldown compared to 90 on Bulwark, Thrill of Battle and Camouflage. Not exactly a short cooldown skill, but still a nice bonus to have over the other tanks.

How come DRK isn't getting guaranteed Crit/DHs on Delirium? Skill is basically the exact same otherwise.

Because WAR has a huge part of its DPS come from 4 skills in Inner Release, while DRK's damage is spread out over a lot of oGCDs. Different jobs should have their burst work in different ways, whether it's guaranteed crits, % damage increases, or skills you can only use every X seconds.

The tanks do actually have differences and advantages/disadvantages in their kits. I don't think they're different enough, but the solution isn't just to add a bunch of stuff to PLD/DRK/GNB's skills. They could all use a big rework.

PLD and WAR were played way less than DRK and GNB in Abyssos and both Ultimates of this expansion. Maybe WAR didn't need as big of a buff as it got, but it needed something. And even with the 6.4 buffs, I think that if the devs had kept Abyssos tankbuster design for the current tier, WAR wouldn't be as popular.
