Had an annoying player in the squad who was yakking to all and sundry in his house but to nobody in game, plus baby screaming for an additional noise. Tried to ask him pleasantly, would he mind turning his mic off, but no response after repeated efforts.
Anyway, I went into the team comms, found the culprit and thought I'd text him instead. I clicked on his name and found to my great delight that I could just mute the tit, ahhh, nice and quiet. I could then hear players that were interested in communicating for the games sake.
What a handy feature.

isn't the little mic bit usually coloured green when someone is talking? that's the way I thought you were meant to tell.
