Hmm.. lets not go back to the "couple of hours" or "couple of days" time frame for switching countries. With the ENY monster going nuts, imagin e what it would be if people couldn't switch for hours or worse, days. That is the sole reason as to why it was changed to an hour, and honestly, if thats all it causes is a few whines because of "spies" than so be it.
Only time "spies" have an affect on your gaming experience is if you are trying to win a war that never ends anyway.
