I’m just curious, why do you think people play co-op matchmaking?
I think they play co-op matchmaking because they need help with some of the campaign missions or they just want to level up and complete some missions without having to play solo.
Also, why is it that you have to wait until you get to a certain rank to play co-op matchmaking?
Achievments. Alot of the achievments in Halo games involve playing with people. Or maybe they just want a laugh playing with their friends over Live 
OP, do you mean co-op campaign or straight up matchmaking like Team Slayer?
personally, i very rarely do campaign co-op (unless it’s speed runs and my partner is host) because i have awful co-op lag most of the time so that’s a moot point for me.
i play co-op matchmaking because it’s more fun with friends. simple as that. and i’m not sure what exactly you mean by waiting for a certain rank to “play co-op matchmaking” because a brand new account can sign into Reach and hop into a Team Slayer game. could you clarify what you mean, please?

When I first tried to play co-op matchmaking, it said I have to reach a certain rank to play it. I don’t remember the exact message but I had to wait until I reached a higher rank to play co-op matchmaking.
Can you explain what you mean by “matchmaking?”

I believe the user means the Co-Op Campaign Playlist.
I don’t but I think it is probably a small but necessary list needed for those that don’t know about forums and networking, etc.
