New pack?

Having another pack sounds like a good idea to me, but I also sort of the like the idea of having Rogues join a pack or face a penalty at some point should there ever be too many. It shouldn't be something as dire as UR CHAR STARVES TO DEATH because that would suck. I don't know many Rpers who are okay with their character just randomly dying. Likewise, people could have their characters just join a pack during the winter and then leave in the Spring to circumvent it.
