Yeah I'm pretty convinced it's something to do with the amount of other people connecting. My problem is most prevalant in the tower and Crucible. I have finished Crucible matches but most run for a couple minutes and then explode. I've gone to the Tower and things run find, but frequently get bee'd. Seems like when I finish a match, the numbers stable -- see not lots of new people loading into the match after it starts. The overworld and strikes work MOST of the time. But when they do crash, it's almost always with lots of other players running around (typically when people load in).
