Dear HTC,
We have vox and voice squelch options. It is time for mission planners to be able to choose who can and cannot join their missions.
As some of us have experienced, some people who shall remain unnamed have joined missions, then switched sides to attack that very mission. As a mission planner it would be great to be able to block such people from being able to join the mission, otherwise, I have no choice to but to cancel those missions since I am not going to tolerate a spy and traitor and get other players killed due to it.
