DRK needs re-tuning/buffing.

Abyssal Drain single target modifier ?

This is a neat idea, I like it a lot. Something like:

Abyssal Drain: Deals unaspected damage with a potency of 120 to the target and all enemies near it.
Dark Arts effect: Restores 1000% of the damage dealt, divided by the number of targets hit.

This would make single-target DA-AD a 1200 potency heal - exactly the same as Clemency/Equilibrium, and requiring a similar sacrifice of DPS.

Well then you poping your CD wrong then Rampart+ The Blackest Night is more then enough For StormSpilitters . And Shadow Wall for the other.

This is exactly what I described in my post. Rampart+TBN or Shadow Wall+TBN for every Stormsplitter. Then in between Stormsplitters you have nothing but TBN, which at most mitigates two AAs.

Compare this to WAR who can just Rampart+Raw Intuition every single one and still have Thrill and Vengeance in between, or if in Defiance, Rampart+IB/Raw Intuition+IB and still have either Rampart or Raw Intuition left over. PLD can Sheltron+Rampart every one, and still have Sentinel, Bulwark, and Clemency for the damage in between.

DRK just has less mitigation options available to it. Its kit is designed around mitigating tank busters with very little to level out all of the damage in between those tank busters.
