Don't care for proxy chat for the exact reason people want it. Trash talking is the most basic of immature behaviors, and while some people can manage to do it with some sense of civility and humor, most cannot.

I don't want or need to hear how awesome you think you are because you pressed a button and twiddled your thumbs well enough to kill me, particularly when I killed you the last eleven times we ran into each other. Nor do I want to hear how "cheap" I am because I shot you in the back because you happened to be facing the other way, I don't plan on whistling to get your attention next time either. Nor do I want to know what you think about my "mama" or my sister, brother, father, or dog. Keep it to yourself.

And sure I don't mind when you give away your position, but I would still rather not have to hear the conversation you're having with the person in the room with you, or the person on the phone with you, or what you like listening to, or what it sounds like when you eat.

Seconded.

And I also hope that the American/Canadian accents are both done by the same guy, and you can tell he's British and faking the accent... badly.
