In my personal humble opinion, I'm certain to myself that Xûr is not RNG by any means. I believe in totality that xûr's inventory is pre chosen. Just by using real life logic anyone can deduce it's not RNG based. How many times a weapon has been sold twice? 3 times only...red death, truth(twice in short time) and suros regime. If it was really RNG we would probably by now had a weapon sold about 3 to 4 times. What a coincidence that xûr has yet to sell only what? 3 more weapons? (Correct me if wrong on this) that's it? He's about to be done selling all exotic weapons mmm....what a coincidence...NOT. Use your logic people. The armor on the other hand it's more limited for each character so we see the same armor over and over again. Yet for warlocks xûr just can't sell anything other than voidfangs and Sunbreakers....mmmm...what a coincidence...NOT. also for the very first time he sold last week the hunter gauntlets...wonder why until now...not a coincidence. Same goes for the no back up plans for titans...only sold once before sold again last week. When everyone in the community is begging for those 2 gauntlets. This whole xûr thing is just pre chosen by a team. Whoever doesn't want to open their eyes...to each their own. Obviously bungie trying to make the armor less accessible. Helmets too have been a bit difficult to come by...that's why xûr also sells engrams. Which then again bungie made it hard with the engrams being random for each class...this to make you think about creating a new class and play the game more. XÛR IS NOT RNG...PERIOD! Edit 1: By the way just want to clarify that I have nothing against xûr...I love xûr and I love destiny. Just want people to open their eyes, xûr is not RNG based...it's pre chosen!
