Sounds a bit like an overgeneralization. I've never met anyone like that and generally from what I've seen, it's nice to have a DRK around for that crazy damage which they still bring.
Reprisal being DRK seems to be only in HW, by the time I was around in SB everyone had it so that's not a WAR specific problem.
Most of the people I know have an issue with TBN coming way too late, not it being unfair.
The DPS issue was a big thing with P8S, overtuned as it was but it did show a glaring disparity that needed fixing. Now there's no worrying about lockout anymore. It just so happens that the devs are late buffing DRK's sustain outside of making Living Dead an actual good invuln after two expansions.

Barbarian tanks are too angry to die but PLD's have quite a good support kit(outside of Cover still being nerfed, rest in peace). The identity DRK should try to follow I already mentioned on the other thread. Lean more into MP management and focusing more on just being a powerhouse with shields and offensives, and getting some sustain through souls and blood. GNB are the cracked cousins that try fitting more into their burst window than mitigating normally but that's how they roll.

DRK could benefit from getting patched up along with GNB, and PLD is already a pretty solid tank that's always a pleasure to see. Selfish is trying to bring others down just to make yourself feel better. That much is already known from the sheer WAR hate and skewing of data. But hey, if you want to pretend WAR's hate DRK just because, disregard this post then. I'd love to see it become a deadlier force personally and most people I know are glad when it gets its overdue buffs.
