Yes Bungie, ALL activities. That includes the raids. Stop giving us the excuse that, "Challenging activities require team communication" Let us decide if it's too challenging. If it is, then people will find teams. At least with matchmaking we can make new friends. Stop with the bs. So many players want this too happen. Do we gotta petition for it?!?
Normal menagerie is a perfect example why raid matchmaking wouldn't work. How many times have you aced 2 encounters and head straight to the boss. I can count them on 1 hand. Another reason why raid matchmaking wouldn't work is that people who already do raids would just lfg rather than going in with a totally random bunch of people they cant kick for incompetence or trolling. So the main group you rely on to guide new players is not engaging in MM, so you just have new players without an idea in the world how to do the raid banging their heads against a wall and then calling the activities too hard and whining on the forums. As for hard nightfalls, it's an issue with collaboration. You would have a random guardian thinking it's a good idea to launch a 980 nightfall when they are just 900, and basically be a detriment to any player wanting to do the nightfall at the intended light.
