a hack idea that's very simple
i remmember a LONG time ago, there was a ha.ck where if you press either F2 or F3 it'd make you switch teams.
it wasn't visual, but you didn't actually SWITCH teams.
if you where in ghost mode for example, and you were a ghost, then you pressed F3, it would put your name on the opposing team, so you could still KICK form ghost team. also if you had like, 5 seconds left on the match, and you were losing, then you pressed F2 or whatever you'd switch sides and instead of getting "YOUR TEAM LOSES!" you'd get "WIN!"
