I think Tapakeg said it best. Once every 30 days, thats all the country changes you get to make. It would allow all the squads that change every month to continue to do so. However it would limit those who come over to cause disruptions and then go back the next day. It will also prevent large squads from sending 1 junior member over to spy, report, then return and send another over the next day. Just my $ .02
