I am fine with the roles as they are now - though I'm not sure if I like the bear. I play werewolves on some other fora and to avoid multiple lynching we choose a leader (mayor, if you like) on day one. If the votes are tied, he or she has the final say in who is being lynched. It adds something extra to the game, because a corrupted leader could turn the game in favor of the werecreatures. Maybe an idea for another game in the future, I don't know.
As for professions, I shall be the woman making crochet scarves all day. Since this is a very useless thing to do, I shall mostly just gasp and bat my eyelashes a lot.
