Suggestion #1: No room re-entrance, everybody is rejoining dammit the channel is unplayable, either you remove the limitations on kicks or make BG rooms non re-entrant at least if you leave you have to wait 10 minutes or something like this and even better if they dont rejoin at all.
Suggestion #2: Mine the main bases in dogfight maps to limit the spawnkilling, you know like in Fort Island which is a pretty good idea to help BG

Fix for suggestion 1: like other games, punish the leaving players by not letting them join ANY room for 5-10 minutes
