Ideas for tweaking a Soul Reaping Build

"Experimental" build I came up with and tested in FoW last night purely as I fancied trying some of the Soul Reaping skills and found it worked quite well especially in the spider cave which is where the wells came in handy, plus 37 energy back from Reapers was nice, and I'm also not in the habit of testing builds on ettins outside Beetletun then say "woo yay!", plus my friend asked if I wanted to go FoW with heroes for a laugh

OK Basically 16 in SR and 15 in Blood as I'm not in the habit of spreading attributes all over the place on "multi line" builds, I stuck the rest in Prot as I used Rebirth as the Res which I only had to use once.

Used the SR Staff of the Forgotten, along with the Crimson Claw Scepter and a desert 27e Soul Reaping Focus.

Reapers Mark
Signet Of Sorrow
Signet Of Lost Souls
Mark Of Subversion
Shadow Strike
Lifebane Strike
Well Of Blood
Rebirth

Basically first cast RM and Mark Of Subversion on the Monk and he goes down pretty fast, the other skills on targets of your choice. I know Shadow/Lifebane are the same skills but it's a good "Spam Spell" same as people who do Defile/Desecrate, and as we had a Hero monk for a build my friend was testing and I had Olias set up as an Orders I didnt worry too much about Blood Ritual although either the well or one of the strikes can be swapped for that if need be.

I was toying with the idea of swapping Reapers Mark for Icy Veins and perhaps putting Life Siphon in but would like to hear some suggestions regarding this.

Obviously not a build to suit everyone but I'd like to hear some views, obviously if a MM's in the party I'd ditch the well to save any arguments.
