i don't know if this is already implemented or not, if it is, my apologies, but a spectator team option would be EXTREMELY awesome.
so many times you just want to spectate but also hang out too.
teams marked with "spectate" have no way to communicate with the gamemode (if there are two teams and one team dies off, the game ends, the spectators don't have to ctrl+k) and they can't pick up items either.
