I have done 10-12 legend and master lost sectors trying to get this season's exotic chest armor. However, not only have I not gotten that to drop, I have not been able to get any exotic armor to drop at all. All I have gotten from the chest at the end of it has been glimmer and enhancement cores. Something is wrong with the drop rate and ability to attain exotic gear. I have heard from a discord server as well as twitter that I am not the only one suffering from this -blam!- unattainability to get exotic gear.
