I'd like to see a system where you can choose whether or not to enter matchmaking. That way if I want a challenge and want to solo the Nightfall (or maybe because I'm just feeling reclusive) I can still do that. But there are times I want to play with a group or need more people for something like the Raid. I haven't played the VoG in three weeks because my friends and I can't find a time for at least five of us to play together. It's frustrating.
