Same exact boat as you, except I play at night when everyone else has gone to bed. I have 0 'friends' with whom to form fireteams and rely solely on matchmaking for thenheroic or I attempt nightfall solo. Optional matchmaking would be a great addition. That way those who want their own fireteams can still go through existing channels to form groups, but those of us that dont't have time to search for groups and hope for an invite, or have enough 'friends' can still enjoy trying these events.
