I think your problem lies not in a lack of matchmaking but in a lack of proper social spaces with chat. It's not possible in this game to log in and chat with people in a major city to form a group or make friends. As an avid MMO and Destiny player I do agree that part of the challenge of end game content is creating your own group, but this game is not supportive of finding that group and forces you to rely on sources outside its game. Therefore what we need is not matchmaking but expanded and vastly improved social spaces.
