Some ideas to improve the custom arenas:
1 – Option “Enforce team”: If you join in red or blue, have to keep playing in the same team until to leave the room.
2 – Kick and Ban by vote: If the both teams vote, they can kick a player or ban him from the room. The room owner can set the time – A) Only kick. B-) Kick and ban for 1 hour, C ) Kick and ban for 24h.
3 – Spectador preferences:
A) Priority to choose the team: If the spectador spend a match only watching and if the room owner permit by configuration, he can have priority to choose a team in the next match. But have to keep playing in the same team.
