I don't run with a mic anymore, because when I do I'm usually screaming at my pub and asking if they are handicapped. However, I have also run with completely silent pub squads that understood what role was needed at a specific time, or what tactics to play in a game mode and field ops. So I say, Common sense wins over mics, almost everytime. Although not everyone in my clan agrees lol.
