Anyone else want instakill sneak attack for vamps on people. Like in their sleep or just an unarmed attack from behind but drain their bloods while you do it?

Nocturne does this now... I just don't have an "Official" quest to back it up.

If they have use to the Vampires (shop owners, etc.) then they may live. The beggars are a food source, they may live.

Everyone else dies. Slowly, strategically, silently, and all for the betterment of the Vampires.

I was actually hoping that biting NPC's while they were awake would do this. It's a shame there can't be another spell like the vampire seduction, but biting them kills the victim instead.
So yea, I would like something like this.
