no no because of this rule.

If there is a Werewolf in the Bar and also 1 or more Werewolf not in the Bar, the Werewolves can also perform a Kill or Conversion action that night.
The werewolves just have to kill the bartender the first night and then everyone is fucked?
failing that just keep their numbers up by conversion throughout the game.
either way its a bit of an odd setup.
