Let me lay out the scene. I'm soloing the nightfall because I like the challenge, but also because the nightfall obviously lacks matchmaking. I could look on lfg sites, which I eventually did when I reached omnigul. When the players can't join, and subsequently get the "permissions changed" notice, I feel bad for them. But when I pop Destiny back up and I see that I was kicked from my Nightfall with a vulture error, I felt that one... Shame. Shame. Shame.
