Am I missing something, or are Dark Knights just terrible?

Hmm, well best mitigation is something at least. Worst damage output is definitely disappointing; I'm guessing that means that DRK is the worst progression tank.

Don't let that fool you, max damage between tanks varies up to 3 or 4% from highest to lowest. Damage isn't a critical factor when picking DRK.

DRK is actually solid as a progression tank due to TBN. Dont know what happens next? TBN and see. You do know and it deals damage to you or co-tank? TBN anyways, chances are it's worthwhile anyways as long as it breaks.
