Just put in the effort yourself to find a group. They want a social game. Talking to people, meeting new people, is the point. If people put more effort into finding people to play with and not crying about matchmaking, they would have a full list of other people wanting to play.

But right now the social aspect is missing things that help streamline the whole thing, full blown mmos have chat systems in place for this Destiny something in a similar but not exact manner. One is to have the capability to travel to the raid area in orbit then while there you can look at people who want to raid, there gear, there class and so on simple yet effective

The need to update the social features in the Tower. I agree.
