Possible DRK changes, HW onward used as a basis

[Undeadfire]

3) The only changes Blood Weapon needs is a stack system instead of a 10s duration. It would be nice to have the haste return to help our spells aoe's come faster since they're stuck feeling very slow.

Stacks are fine but the increase speed would require potency cuts on their GCDs.

Scourge has the same effect as it did in HW, make it whatever potency or whatever is needed for balance, and a DoT.

DOTs are really powerful on their potency level and current stats, I would generally be careful with this.

4)Bring back Blood Price, and it returns 200MP for every time you get hit by an enemy.

This is banned from tanks since Shadowbringers, it's never coming back, ever, cooldowns based on this only generates tank favouring for more DPS, and can really screw raid balancing.

5) Delirium should not be worse inner release, leave that gimmick to Warrior. A couple effects I have in mind are to either bring it's MP gen back, or make it refresh the cooldown on carve and spit/Abyssal Drain

Potency changes.
