Ok, so today I get on destiny and I go find Xur, and everything is unable to be purschased. It says I'm lacking exotic shards. But the other thing it requires is the item itself. In order to buy the suros regime auto rifle, I have to have it ALREADY. Why? How is that possible? I want exotic gear. I'm only 8 levels away from max and my guns and armor is all common/uncommon/rare. I need exotic or legendary stuff. Help please!
