One- please do some research before talking to me like I’ve never done a key before, you don’t know who you’re talking to.
Two- there’s a reason why people invite dk’s into 20+ keys and people hardly invite rets, even though there’s more ret players than dk players in general.
Three- they are on par with rets.
You’re not special so quit acting like it; it’s unbecoming.

There’s almost 2.5x as many Rets in 20+ keys as DPS DKs. When you change it to timed runs, it’s almost 3x.
DKs bring Brez and AMZ.
Ret brings Brez, Freedom, LoH, 3% damage reduction or a 2.5% (averaged) damage increase, Cleanse, BoP, and Sac as generics. Ret can solo Incorp and Afflicted.
No, DPS DKs are not even remotely close to being on par with Ret in M+, and the stats very clearly back this up.
The only dungeon where DKs excel over Ret is Waycrest since Judgment pulls through the floors & ceilings there.
So do DK diseases and AoE’s. Happened to me the last three runs.
2023 and the Z axis is still glitchy. Very cool 
Been playing DK since they first came to the game. You had to be Lvl 60 to start one, and only one per account and only blood elf’s. Now all that is gone 
Reason I switched to FDK was I played a different MMO, BDK was like the Tanks there, Start Atk Go get a coffee, the make a sandwich come back pick up loot, and start again. At least with Frost it feels more like you are doing something. Sometimes I’m really not sure what, but I just keep banging away. And if I get to a tough spot I bring in My BMH, at least then I can get a step or two ifn I gotta run. DKF can’t turn your back and run That Is Sure Death, and really who want to go down with everyone watching. At say I tried dammit. LOL I guess I just enjoy the struggle.
