Yeah it would seem an easy program to make sure the teams start with even numbers.
And sometimes you’ll see pretty uneven numbers mid or late round. If one team is smaller then at least dont let the bigger team continue growing until the smaller team evens out. The software should handle this better. I dont know if they just tried to get too fancy with their algorithms or what. Its not rocket science.
I think they made a total mess of the lobby system in BF1. It doesn’t seem to have any idea of players joining or leaving. It’s like it allocates teams based on the last game population and sticks with that no matter what happens.
In this regard, BF4 was much better, if I recall correctly. The lobby system was excellent.
