Some people also collect to collect. Bungie has mentioned a number of times how seasoned players should brandish their weapons from the original game to have newer players asking "Where did you get this Shadow Price?," "I have Her Benevolence, but where did The Supremacy come from?," or "Wow, you have the original Iron Banner armors? You must be a total badass!" I have collected almost everything in the game, and I will admit that I don't use most of it, but there is a lot that I do use. I DON'T want to part with them!
