Better yet, for those of us who have terrible luck and would end up getting the same weapon each week. He should sell armor like he normally does, and have all 3 weapons engrams and you get a choice of 1 per character per week (they will still cost). That way us who have terrible luck have multiple chances at getting what we want while those who get what they want first try can have chances at other stuff. I honestly think that Xur is fine as is and wouldnt need changed unless Bungie fixes this flawed RNG system, but if it comes down to engrams, i dont want just 1 per week, considering that my first Gjallarhorn i have ever gotten was from Xur, especially when every other droppable exotic has dropped multiple times. I get that you want to feel special, but in pretty much any game, there will be a preffered weapon that the majority of people will use, even if its not better than any other.
