Would you probably allow Guilds to have Multiple Strongholds? That way it would allow RP'ing Guilds to have different Area Settings, More RP Capabilities, and Increase RP Experiences, Environments. It would also improve Guilds trying to run more than one Theme/Setting in their Guilds; Allow less stress and constriction on Role Players, and their Guild Master. Like opening a structure within the Guild, and allow each branch holder to have their own Environment, to improvise and create immersion in the Guilds.
Just a thought..
