I have friends, we just haven't gotten around to playing together. I don't play much of the endgame content. If they were to add matchmaking for raids n' stuff, they should make it a requirement to have a mic, and they should also add a sort of lounge where said fire teams can just talk and get to know each other and plan for a raid or something else before they do it. That's how endgame matchmaking should be in my opinion.
