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?
I like the idea of a clan vault. Add good weapons / armor that is too good to dismantle, but not as good as what you are currently wearing. Creates teamwork and comradery. Also, nice surprise when you log in and go to the tower and find a better weapon in the clan vault to trade!
