We (maybe) did it. DRK is being looked at.

DP is "worth it" for the DPS and less Mp consumption than AD.

It's "not worth it" for the threat.

2 GCDs

AD > AD = 240 potency (240x) -2640mp
vs
HS > DA+DP > SS = 640 potency (240x + 400) -1320mp(grit) or -2520(no grit)

If you do 3 GCD

3rd GCD is another AD.
vs
3rd GCD is AD.

Every GCD after the 2nd is AD, meaning the damage difference never changes.
The only difference is that AD offers threat, DP doesnt, it adds blind and more dps to 1 single target/saves mp

The problem lies in the fact DP is such a minimal increase, AND the fact there is NEVER a reason to not DA it. Where as some DRK abilities have decent reasons to not DA them. Such as CnS where you use the MP for AoE scenarios.
(Personally Id make it a single target attack, and replace blind with -5% dmg dealt, like reprisal. DA would then make it an AoE, giving us the 1st AoE version of reprisal in the game.)
