Re vamp modding in general: I understand that when you get down to it, whatever El Presidente says goes, because it's his mod made for his amusement, but I really hope he would make any vamp-related options configurable. More challenge and less T-ratedness may or may not be what everyone wants every time, especially considering wide variety of opinion on what exactly vampire powers and weaknesses ought to be.
It would be like leaving 12-woohoo permanently on with no way to switch it off.
