You're definitely not alone. I have buddies that collect as well. I just want certain ones. The ones that I don't find useful, I don't usually keep, the OCD won't allow it. lol If I can get a Suros and a Gjallahorn I'll have all the exotic weapons I want. I have several that either sit on a player or sit in the vault unused. I have to fight the urge to dismantle them. haha They are a nice change of pace from the norm though when I do switch and use one.
