I ran like 20 of these damn things and i didnt get any exotic chest. Most of the time its just glimmer or the occasional core. shards and cores should be guaranteed drops as well as legendary gear. That way you don't feel like you wasted your time when it doesn't drop exotics. It ahould drop the exotics way more often because this lowass droprate sucks, how are we to farm the armor with the stats we want if the drops are like 1 in a -blam!- million. May change it to drop every other run or something cuz the rng is frustrating.
Master lost sectors are the same. I've just done 10 master lost sectors some flawlessly & got 0 exotic engrams. It States IF SOLO - Exotic Head Armor (Common) Enhancement cores (Uncommon) I call BS I got Zero exotic engrams to drop but got 10+ enhancement cores & glimmer. . I'd like to know what Bungie's description to common is. Perhaps they need to look it up in a dictionary!
