i dont think there should be a seperate chat thing to talk privatly, instead, i think when u play a team game u should be able to press y or some key to talk to members of ure team and t to talk to everyone on the map and when its just normal play no teams then maybe people could meet up and when more then one person is near each other maybe they could make another button, like u or something close to the others, for talkin just to the person within a short radius
