In the Giovanni Mansion, you really only have to fight the twins. The rest you can trick, deceive or outrun (well, mostly). Fighting is also limited in Leopold (except the crazy vampire hunter)
Why not ?
Hollowbrook was part of what I referred to as "uninspiredcand tedious" previously
Really bad compared to the rest.
Hades' mileage may vary
The only characters (well, Brujahs and Gangrels actually) that I havent tried... :-"
