My idea is:
Payers with the exact same clantag (for example [xyz]) should spawn next (100m radius or so) to other players with the same clantag.
Then it would be easier to team up with friends.
To exclude abuse each player with that clantag who is already spawned must then vote "yes" or "no" to let the candidate spawn or not. If only one votes "no" then the new player should spawn like always. Vote timeout 10 seconds.
