Remove the tracking of the gb. It's annoying that if you dodge backwards your oponnent flies to you like a freaking missile and you can't do anything against it.
Furthermore improve the matchmaking system, freaking hell. 80% of the time the lobby closes because there aren't enough players. Remove the countdown if there aren't enough, it's that simple. There are a lot matchmaking systems which work great. Like Overwatch, GTA V, Battlefield, etc.. The lobby doesn't close. It searches for players while you can decide to wait or leave.
