I got rid of vamp on my stam NB. I miss the sneak speed alot, but I feel like this patch really nerfed the stealth attack element of the game, so I can live with it. Sneak speed was the real reason I went vampire in the first place.

Other than that I am glad I did it. Having terrible health regen got really annoying, as well as trying to do dungeons with alot of fire damage. I started feeling like a burden on my groups because I had a hard time managing my health. I honestly didnt feel that much of a change in my regen, though im sure it helped.

In terms of abilities I only really used bats. It was a good ultimate, but I still do ok without it. Soul Tether gives me a heal if I need it (Never played a templar so I don't know what you could replace it with). I feel like ability slots are limited, and now that you have to have a vamp ability slotted to get the regen, the abilities aren't worth it. Also the couple abilities are all magicka, and Mist form has a high cost, which depleted my magicka pool quickly on a stamina build.

The problem in IC seems to be every mob is daedra, so everyone runs around with camo hunter and dawnbreaker which can make you an easy target. Before IC I felt like some people used these abilities, but not near as many as now.

All in all, I think I am happier on this build as a non-vamp. I'm building a Magicka NB build, and may give vamp another shot, but am still undecided.
