1) disable ffa and bots in team rooms (theres a room for this so no point, sometimes it destroys party)
2) add a bots player coop teams room. if its less 6 players it will fill up the teams with bots. (1st player will play with 2 bots against 3 bots, next player joins it becomes a 2bots 1 player vs 2 bots 1 player... and so on...)
(new player would be forced into teamgames and this would initialize party)
3) a match opponent finder: i select i want to play team games, minimum 3 on 3 this would make sense to the steam release topic i just read... i would use that, and some more "waiting for a good stack/game/map"-spectators probably too (maybe not anymore if work has been done to the rooms somehow)
what do you think
