I have spent the better part of 8 hours in Dreaming City grinding kills, pubs, chests, lost sectors. That being said, I still havent gotten a Corsair Down. To put the icing on the cake, I got on my alt and within 10 minutes one dropped from a Scorn kill. I am IRATE to say the least. Thank you Bungie for yet another notch in the belt of disappointment. Cant even complete an exotic quest.
