Rebuilding a recently rebuilt Shadow Healer

Flowcyto gave me this great build below, but with the Darkness pass, can it be approved upon with some of the new powers? Does Spirit Reverb still work off REC/END. I was already Presence PSS so I have that going for me. I figure to tweak it just a bit. I don't use Grasping Shadows a lot due to a slow charge up that I believe can be interrupted. I was going to rely on Vengeance w/Redemption Denied to Proc Paralyze and Stun and the specilizations as it has a quick charge and works well and take Shadow Embrace w/Advantage to heal me and clean trash.
