Rework all mitigations for tanks

[StarlessSky]

It is not fine that tank current so not balance..

It is litterally game breaking and meta shifting which no one should agree on it

Dark knight weather need overhaul or need to have clear purpose

If there's a tank that's unbalanced, it's WAR. DRK is perfectly playable in dungeons, just slightly more punishing due to a relative dearth of self sustain and TBN costing MP/losing value if it doesn't pop. With the addition of the excog on Shadowed Vigil, even soloing bosses from high health has become much less difficult—though I think that it's become borderline expected for tank kits to allow for this is indicative of how ludicrously overpowered they are compared to dungeon bosses' damage output.

IMO its survivability on typical trash pulls is about where the other tanks should be. It only feels weak because it's being compared against WAR, which has a functional invuln on nearly 33% uptime, and PLD, with Holy Sheltron and 4000-ish healing potency per minute baked into its AoE DPS rotation.
