Bungie really need to tell us what the drop rate chances are and the "Bad Luck" increase, especially for Raid Exotics, I have 120 DSC clears (84 being actual drop chances - not sure if 4 Ball Challenge counts on top of that) and to still not have a weapon that someone with lucky RNG could get on their first try is ridiculous (I have 3 in the clan who got it within their first 3 characters) That's 28 weeks, over 1/2 a year (I finished my first DSC within an hour of Contest mode finishing) of constant and consistent activity and not to have a system in place whereby after 30/40/50 whatever unique completions you should be able to unlock it from the exotic kiosk in the tower. There should be no way that you should play that much covering two full in game seasons (even a new raid is out now) and not have a weapon from something where you have done everything you possibly can and it is just ridiculous drop chance that is the issue. On top of that this weapon is also required to get the seal!!!
