I don't want him to sell it. I like the rarity of some weapons in the game. I don't care if people have it or don't have it, but I like the rarity of some weapons. If everyone had every weapon in the game, there would be no goals when it comes to the weapons in Destiny. I don't have all the exotics even though I play almost nonstop, an I like it that way. I can make it my goal everyday to try and get those weapons I don't have. I think Xur should only sell the more common exotic weapons, and the other ones are acquired by trying to receive them from a random drop anywhere in the game.
