Is GNB bad or is TBN too good?

DRK is way worse than PAL and WAR in dungeon pulls. For the love of god do not nerf us any more, we've already fallen far enough.

That is simply not true, DRK now has the best AoE damage of all tanks, thanks to Flood of Shadow/Darkness being weaved between Quietus Delirium spam, on top of Salted Earth. (not to mention Abyssal Drain being oGCD)
The Blackest Night also is the best self mitigation in the game, not only for being spammable, but also completely DPS neutral while increasing your effective HP by 1/4 of maximum value.

DRK is just broken in every way, especially in dungeons. I also suspect that DRK is going to be mandatory for high-end content.
