Master Lost Sector drop rates appear to be lower than the expected 33%. Between myself and another clanmate the two of us have completed at least 30 Master Lost sectors this season and have only had one piece of Exotic armor drop between the two of us. For the first few runs its seemed like bad luck but after each of us hit the 12th clear or so the math just doesn't seem to add up with what should be roughly one out of three clears. Thanks for your time.
