I can't recall if this has been discussed in werewolf but in wwjr, the game that is playing now
The Broken Souls, there are 2 (true) seers. Ironically enough I was one and got killed after I got killed from this one

. Anyway the two seers worked as a team-PMing only at night and dreaming of one person. There were 15 players with hunter, ranger and 3 wolves. It doesn't mean an automatic win for the innocents (and we wouldn't want that) but it seems to balance a little better. I just thought I'd throw that out.
