What happens to us with 6 or so friends we like to gather up with and play bf as a squad? You encourage and build a game around team work and then make it where you can't keep your friends together with squads of 4 and team balancing.
Why not 6? We get an even number is squads and friends can play together in groups. If not you better have servers set aside that have auto rotation turned off for large groups to play together.
