When I host TDM that I want to require team effort, this is usually compromised because I can't expect everyone to use team chat and others aren't willing to switch over. What I'm requesting is that in a TDM the two teams are incapable of talking to each other without having some symbol in front of their chat, which would serve as OOC (out of character), for example, if I were to chat normally, it would go only to my teammates, however if I were to say for example "# (chat here)" all players in the server would see the message as if regular chat was used.
