Hmm not keen on 4 people per squad. It works on BC2 cause basically the game works on a smaller scale. However they're saying the maps will be larger then ever before blah blah blah.. if you have 64 players on a server, 8 squads each side and no commander to co-ordinate, it could lose the battle feel its setting out to have and that is my one big reservation about this game.
Squad size dependant on server size may be an idea, but I'm guessing they're passed ideas now..
Generally though my feelings are same as Piggys
