I mean seriously. It needs to happen. I can only use 1 exotic weapon at a time, which means that the other 16 I have are in the vault, along with an obscene amount of legendaries because I'm a hoarder. I want a shotgun, fusion rifle, sniper, machine gun and rocket launcher of every damage type, and there is no way there is enough room. Or at least a way to check you're inventory without having to load in your character. That way I will at least know who has what gun. Come on Bungie. You have so many people asking for this. Make it cost like 20k glimmer or something for 4 slots. Or 100 vanguard/crucible marks. Make it a large amount of something. Right now there's no real reason to have glimmer. Come on now. It's a month after launch, and people are collecting more and more weapons and materials and need more vault space.
