Lol @ all the anti vault space protestors. For me, extra vault space has little to do with how you manage your gear or if you're a hoarder or how we just can't let go of things. It's all about currency for me. Legendary gear that you won't equip is still valuable to me because it breaks down into legendary marks, weapon/armor parts, and glimmer. Marks and glimmer are capped at a certain amount so I throw all my legendary stuff into the vault to break it down for currency that I know I'll need later. Is it game breaking for me? No it's not. But it would be nice to not have to waste currency because there's no more room to store it. It's a convenience thing, nothing more.
