Even the scoreboard doesn't show who is speaking at the moment. How do I know if radio chatter relates to my position or two buildings down the street. Bearing and direction are useless if I cannot differentiate if it's proximity or radio. This makes PUG teamwork harder than it should be.
At least let us see who is talking at the scoreboard screen so we can mute the dude spewing racist slurs. Even COD has this functionality.
