For me the problem is not how you obtain it. It's all luck in the RNG. You however did put in the effort to get that reward. My problem is that you've taken something rare and special and made it common. What is the fun of feeling like everyone else? I'm not saying that because I had this gun before xur sold it that I earned it and I'm better. I'm saying that it made me feel special, not better. There is not point in all being the same that's lame and boring. It's being something different by pure luck that makes this game fun. It isn't fun if all thirties look the same and wield the same gun. That is the problem is nothing is rare. Nothing is special. So what is the point in playing if I can wait the next week to get another rare exotic? There isn't.
