Man, I don't have enough friends to fill a squad, let alone a server :(
Ive been slagging this game off for lack of content but 8 maps by the end of the year is pretty good. In fact its excellent, why? Because its free
You don't have to fill the server with friends. When it drops, just create a Private Match and tell people. Make the settings appealing and folks will want to play on the server.
