Make comms default in-game

I think it would improve games greatly if there were a default comms client in-game, i.e. it gave all team members an easy and simple way to connect to a temporary comms server to talk during a game. It would dramatically reduce toxicity as people are less likely to rage at teammates over voice chat than through text. It would also allow for context in suggestions for courses of actions and build paths - saying "let's do this," or "you do that" is less effective than talking to someone and explaining the reasoning and getting their feedback.
