Regarding seer-types, I think weretiger should have a kill but not scry, and that Death needs to be changed from "Devil 2.0" (for asymmetry reasons). PI is a neat mechanic and I think it should probably stay.
How about Death is the third starting vampire, and can detect the team of any player who uses a night action (successful or not) against one of the three starting vamps? Death could be used for the vamps' nightkill purposes, but would not be able to counterscry that night. Death also could not inherit the title of Drac 2.0.
I also think this could simplify the vamp/wolf nightkill interaction, which has become somewhat cumbersome in an attempt to balance out the interactions. It could also be an excuse to add the Really Hairy Guy (scries as a wolf to oracle-types, which would include Oracle, Death, and Air Bud in his new proposed role) as an innocent role.
