User blog comment:Derp2000/Matchmaking in Weekly?/@comment-1158256-20150224230725

Having match-making for weeklies will be nice. I know there are a few that I avoid if I know I can't do them solo.

Not having match-making in raids still makes sense, though. I believe Bungie omits it there, to encourage you to have a cohesive team of people you can trust to have your back. Sites like http://destinylfg.net/ and http://the100.io/ are undermining that a bit, but I can still understand that mindset.
