only exotic left for me is ghorn and I have gotten every other exotic weapon 2+ times (thunderlord 7+, IB 5+, Vex 4+, Suros 3+) and closing in on 750 hours.. jesus haha It def seems there is some sort of pattern where weapons and armor keep repeating themselves once dropped or bought from xur. For instance, Praxic Fire was sold by xur two weeks ago. I buy one Friday, get a legendary chest engram later that night, and turn in to cryptbish for another praxic fire...seems odd to happen that soon after. Not trying to make this into a rant because I love this game and even if ghorn dropped I would continue to play with my buddies. It's just almost bungie knows certain gun/armor have a power lust from players which ultimately will make players come back for more.. there is no other reason for me to be hitting the gorgon chest and atheon 3x a week still... I guess i'll keep chasing the mythical unihorn each week watching it drop again & again for players that already have it, including crucible drops hah smh
