Due to the wonderful RNG system in this game, I've managed to not yet get my hands on G'horn, Suros, Red Death, Monte Carlo, Hard Light...but I've done four complete hard runs and got the Vex three times. Personally, I'm reaching the point now where it feels like it would make more sense to run it on a difficulty where an exotic can drop, but not that one. EDIT: Looks like there is some interest in doing a run this evening (16th). I'd certainly be up for that at around 8, ideally.
