People shouldn't have to turn off mics because they're finding one person toxic so instead they'll just report you to remove the person as a factor instead of being forced to turn their mics off.
This is nothing to do with mics. This is all over the text chat in the game. It's up the top left of the screen. There's an option to turn it off. And to be honest if somebody presses the what a save quick chat prompt (I think if you press left and down on the dpad it types that) and that's enough to make a guy sit there and cry for 5 mins I think he's the one who's toxic and not suitable for online gaming.
