I don't main DRK enough to realize this, but does your shadows HP drain skills funnel into you? I never even noticed or took the time to look.

Because if it doesn't then that would be a perfect opportunity to have your shadow - Souleater, Siphon strike, blood weapon, abyssal drain, carve and spit, Bloodgauge would also funnel to the DRK as well as TBN breaks would funnel to the DRK for free MP.

This would fix quite a large portion of what DRK is lacking on a 2 min cooldown.

This would make delirium and Living Shadow be very powerful to offset, offer choice, and this would ultimately increase DPS if your living shadow is giving you heals and bloodgauge. More flood and edges, more MP, more bloodspillers or quietus. But if it already does then i'm DRK ignorant. I main pld and war for tanks.
