Success? Please explain.
The fact that, looking at your gear, your only life regen mechanic was relying upon Sever. This strikes me as a "putting all your eggs in one basket" scenario. Compared to Genghis Khan, who ontop of his sever has 5.7 LS, and 1k life regen. I imagine that if he was to get around 1.6k LoH, he'd be able to handle a Sever nerf.
I just equiped it to see what it does for dps and the 22% additional demon damage, I wasn't aware of the LS proc. With shield I am almost immune to most monster/elite damage anyway.
