YES, not enough inventory slots!
NO, just dismantle/discard what you don't want
We each get 60 slots total (right?), anyone think that's just not enough? Especially as you progress further into the game getting more exotics?
Bump, we need unlimited vault space, why trow us a lot of great exotic weapons and armor if we have to sell them or trow them away? "Oh, you'll get better armor so trow away the other" no, I want to collect the things I work hard for. Please Bungie, Deej, who ever is reading this from the developers, make the vault unlimited to us.
