This isn't really a team based game, so it may be pointless in that matter, but otherwise, I believe it would be an epic idea. I mean what if you and your friend were just having a private game, and he was trying to tell you a move, through text! It would take 1/10000 of the time to just say it for ya mums sake! There is legit nothing wrong with this idea, and removes the point of having to download 3rd party software which would just clog your PC even more than it probably already is. It would BARELY increase your bandwidth usage, even if it did, this game hardly uses hardly any anyway. And DUUHHHHHH there would OBVIOUSLY be a mute button for all the screamers that could even get kicked if they are muted by more than 5 people.
