This is kind of a dilemma.
Over the years if I remember it correctly, Hitech doesn't really like country loyalty and the social results. He doesn't like squads over a certain size and the social results. Combined, you get static populations of tribal loyal, country loyalists with the social results. Switching country at will, or with a shorter time multiple would tend to erode country loyalty in favor of personal gratification. Might even lessen the drive to join squads in favor of fluid associations of the moment. But, then it might drive late night limited time less skilled players out of the game. Because they can never catch a break from getting slaughtered by the same hand full of players who just seem to be everywhere on a map the size of China.
EU and Aussi time I feel sorry for. During their time, jumping at will would be helpful to their game experience in finding someone to fight. 90 players or less on a map the size of china can be depressing.
