I've been at a nonstop grind for 9 hours trying to get the Braytech Osprey with zero luck. My brother (who's kind enough to help me) has gotten 4 osprey's, 3 exotics, and 4 Prime engrams. I have crossed over the 100,000 point threshold, I have all three emblem variations. According to my game history I have completed 27 nightfall strikes in this time period. Why is this happening to me???
