EDIT: woops.
I did the Chaperone strike last night solo. Got matchmade with a party of the two worst players I've ever come across. Void shield psions? Just kept spraying with Zhalo, doing next to nothing damage. Last guy standing in the tank section? Instead of running to a corner to hide, he runs into a huge mob of cabal trying to revive. In the end I solo-ed the tank with a black spindle. First shield brother was about to die, so they killed him with their primaries. O.M.F.G. I left them both dead while I solo-ed the 2nd brother. I loaded up the strike again to find two guys in the boss room, so I got lucky I didn't run into those two idiots again.
