People call us hoarders crazy but when the inevitable necrochasm/auto rifle buff comes, mark my words; these forums will be flooded with posts from people who wish they didn't trash their guns. That's just one example. If trading were ever implemented, imagine the one gun you've never gotten that you could have traded for if you just kept one of your valuable duplicates to trade with. The list goes on... I know for the casual player the vault is probably fine. But what about the people who have been here since alpha, and have been curating these goods waiting for the next word from bungie that they are neutering one weapon type and turning another into a god? We were prepared for that, and we'd like to continue to be prepared. I'd sooner stop playing destiny all together, than stop collecting/keeping equipment. And that means no more money for bungie. I can't be the only customer out there thinking that way.
