1) No raid or nightfall matchmaking cause many people want to solo it or we will have to deal with AFK teammates like tiger strikes. 2) In the game as of now, but nobody even uses it though it is in the game. 3) Could be greatly abused to get a lower level better gear. Ex: Lvl 24 joins strike and lvl 30 carries him through. Lvl 24 has chances to get armor to reach 30 by doing nothing. Though matchmaking would be nice, I think Bungie should fix some problems before doing this. My argument is that there would be a increase in bottom feeders. People who do nothing to get the best gear. Even if it was an option to turn on or off, there would still be people who are doin it cause they have no friends online and need to do the raid/nightfall and aren't skilled enough to do it themselves. They would then be filled with perhaps at least 1 AFK person and make the raid/nightfall still impossible to do. So I don't think so.
