Well mate, unlucky for you, buying items from Xur is the only way to actually "EARN" an exotic. You see, every week, a new strike comes and offers 9 coins. That's the weekly heroic strike (for those ignorant baztards). As weeks go people start to stack this "strange coins" with the only possibility of spending them in, you guessed right, that elusive bastard Xur. When you buy an exotic, your actually earning it through simple exchange of items and eventually, your not relying on luck. #letthewarbegin
