Keep voice chat out!
I do not want it to be meta to use voice chat. I have no desire to talk to randoms whatsoever!
I'd rather sit at the DMV for hours and hours and hours than listen to some squeaker brat cry about ganks in my headset for 30 minutes. Or worse, some man-child who takes a video game personally, and self righteously denounces everything anyone does in a non-stop monologue with his 4 letter word only vocabulary.
