It might’ve been removed since the nuke. I’ve seen people kill all the REDs after a trick order and no “freekiller defected” ever happened.
This is a good idea though if it isn’t actually removed yet. It does more cons than pros.
I agree with having a default TF2 map to play on. It could be fun to play since Casual is filled with bots and aimbotters. It could even have RTV so the server could bounce between different vanilla game modes.
