Like the bloodless thing on undead, in my experience Drac and sanguine were jarringly good, and my Drac worshipers were not really taking either the prep or undead killing penalties seriously.
I do have an UI suggestion - what would help IMO would be if the different buildings had visible labels that needed no mouseover. So you could see where the "Blackmith" preps are, and where the "elf", "dwarf" "guild" and so forth preps are without mousing over, selecting anything or having to know them by art (especially for race/class combos which change artworks depending on when you select what).
EDIT: Somtehing like this:
EDIT2: And obviously moving the blacsmith preps a little bit top and right to not have a cluster of preps right next to each other wold help as well...
