Seriously at that point you're just being redundant. If you have to acquire something difficult, just to get something else difficult, why don't you just cut out the middle man? That's an extra nonsensical step. Really you were voting "no" by your answer, yet your weird semantics caused you to think you meant "yes".

So why not just say no? If you add yet another currency that is "much harder to get", aren't you just really talking about etheric light? No need to complicate it. Xur and etheric light is a no.
