I've run this lost sector 64 times on legendary difficulty with all of them being full platinum clears while only getting 10 exotics to actually drop. The runs themselves were straightforward, only taking between 2-3 minutes per run. As I went I kept a tally of when I got exotics, what I got, and how many runs I got nothing between exotic drops. This looks alright on paper, but it's only a 15.6% drop rate compared to the roughly 25% it's meant to be. From what I recorded, runs 1-20 had 8 exotic drops (40% drop rate) while runs 21-64 only had 2 exotics drop (a 4.5% drop rate) Is this just once-in-a-lifetime bad RNG from runs 21-64 or are the drop rates falling off after a certain amount of runs? Help would be appreciated.
