Hey I have a crazy idea to make teams; it is somewhat complicated but stick with me on this!
Start a 20 man server (assuming 20 players/4 teams obviously); have EVERYONE autojoin red/blue and play out like a 20 min map whereever (could be your chance for gravelpit!)
After the round, we divide up teams like so:
Team 1 gets: Red team places 1,5,9 Blue team places: 4,8
Team 2 gets: Red team places 2,6,10 Blue team places 3,7
Team 3 gets: Red 3,7 Blue 2,6,10
Team 4 gets: Red 4,8 Blue 1,5,9
That way the teams should be “relatively” even
Or you could do the same method but
Team 1 gets Red 1, 4, 5, 8, 9
Team 2 gets Red 2, 3, 6, 7, 10
Team 3 gets Blue 1, 4, 5, 8, 9
Team 4 gets Blue 2, 3, 6, 7, 10
I know that is a little complicated but you said you wanted fair teams rite???????
