TBN - Give TBN some form of mit. Possibly merge Oblation into TBN as lets be honest - you’ll always end up using this with TBN.
Heal based off of the % left of the shield on expiration
If TBN is consumed fully - heal for a % of max HP missing
- Give TBN a 12s HoT
- Give TBN 10% - 20% mitigation
- Make TBN cost 0 mana - To Balance this, make TBN recast 25s so you can bring it inline with the rest of the tanks 25s mitigation.
Note: These are merely suggestions

Dark Missionary - Simply make this unlockable at level 70 so it can be used in earlier ultimates/dungeons/content.

Oblation - Either merge Oblation into TBN OR give Oblation a simple HoT.

Lastly - Class Identity / How it feels to play.

DRK for me personally aesthetically is probably one of the coolest looking designs for a class, but I do admit I feel the class lacks the power in its attacks. For example, comparing Bloodspiller to Inner Chaos, Fell Cleave, Atonement Combo or even the Continuation combo, it doesn’t have the flare or weight the other classes have. Blood spiller just feels incredibly light and doesn’t have the impact the other weaponskills have.

With class Identity - I’ve been left trying to understand the decision to give DRK the trait: “Enhanced Unmend”. I really cannot begin to understand why this is even a thing. At a stretch, I could understand having it back in Endwalker as we could get some extra usages of plunge outside of savage/ultimates. It serves some purpose in dungeons and just killing trash mobs out in the open, but I find it utterly useless in Savage and Ultimate raids.

In the nicest and politest way - Please look to change this. An idea would be to change “Enhanced Unmend” into “Enhanced Bloodspiller”. As mentioned in the self-sustain section, the idea would be to give DRKs Bloodspiller and “Enhanced Delirium” trait a healing effect with a cure potency of 400, just like PLDs “Divine Magic Mastery II”. Every tank has a trait worth something, but DRKs “Enhanced Unmend” just doesn’t fit. I cannot stress enough that this needs to be addressed.

DRK was fun because of the amount of buttons we had to press. Yes, it wasn’t for everyone, but I feel the job has been stripped bare of what made it fun to play. We also need to think about what the classes identity is.
