What would a new tank even contribute at this point

strongest mitigation suite

*Magic Mitigation
I'd say PLD has the strongest mitigations overall. Especially with the reworks.

Frankly, I find more than a little silly you're insisting Dark Knight is terrible to play because it can't match Warrior in dungeons? Who cares? Seriously. They're dungeons. Not only are they so pitifully undertuned nowadays tanks can solo them (yes, even DRK) but Dark Knight is far from the only "unbalanced" job in a dungeon setting

Kinda agree, though I do think it should be noted that trying to wall 2 wall pull with duty support AI is significantly spicier on GNB or DRK compared to WAR or PLD. If you look at the data we have WAR packs about 1.5x as much self sustain as DRK or GNB (who are basically tied for lowest), and while the content is easy enough that a skilled DRK can navigate it,I don't think DRK could solo an EW dungeon easily. Its mits are strong yes but they're not 100% uptime, any damage you take would stick so you'd probably be forced to wait for cooldowns at some point (mainly living dead). Its definitely do able but not in the way say PLD or WAR would do it. But I don't think that matters much, I'd argue its hurting healers far more. WAR's design makes dungeon healers pointless.

Its optimal to run 3 dps and a PLD or WAR into a dungeon, healers are only there because duty finder forces it. I view that as an issue, yeah the content is easy enough where it doesn't matter but who wants to feel like a burden like that?

I honestly think the sustain creep the game is facing right now could spiral out of control very easily, and I'm worried that the next expac will be giving DRK and GNB their own Bloodwhetting, as thats usually how they handles tanks in this game. One expac a tank gets a cool thing, next expac all the tanks get it. Happened with Raidwide mits, Gap Closers, TBN equivalents, Given how much casuals complained about sustain for tanks this expac I really can't see a world where we don't see something like this.

Unfortunately, with how Dark Knight is designed, it simply can't be the strongest tank without dwarfing the other three. It plays too well in the two minute meta and essentially gets free resources whenever there's downtime.

Now this one I agree with, DRK is a balancing nightmare in EW simply due to the fact its the only tank with a real 2m burst, Yeah GNB has bloodfest, but thats no Living Shadow with 2 charges of Shadowbringer.
Honestly even if its not doing the most damage overall, a lot of fights heavily reward what DRK does over the others due to phase changes/downtime ect. Doing big damage in small amounts of time is always going to be superior to doing bigger damage across a long period of time.

I honestly view DRK a lot like old PLD and why it was reworked just as an opposite side of it. PLD played too little into the 2m burst meta, DRK plays too much into it.
