This according to this comment, my game group is large and now we can't stay on the same server playing together, because it sends them to another server at the end of each game, we want the server to stay as it is and in the same region and that they only fill the empty spaces with other players in case there are, we can't be looking for empty servers to be able to enter all together and that it can only be for a single game. in BF3, Bf4 and Bf 1 this doesn't happen. Battlefield communities are large, with more than 4 friends playing alone.
