Thanks for the info. When I meet a troll I tell him he is one of us

well, dear ckdamascus, seems that we ended in this discussion alone

I was thinking about playthrough with ancient vampires. No crazy challenges (hopefully it will be challenging enough), just nice game with vampires only.
So I want to ask - has anybody tried it? Can they be made self sufficient with their drain ability? I guess with very occasional use of eviln it can be done...
