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?
For the people like me that collect cool weapons and armor i can fill it in a few days and with just one character. For a game with hundreds of great items 20 a type is like not having one at all.
