maybe not sold by Xur for strange coins, but to make it harder, as the PoE might be tough, so to mix it up. make the new trader give you a chance for it as well ( It will never be sold by any form of vendor, we all know, but oh well ) E.g. 10 motes, 10 strange coins, 10 shards and 5000 glimmer or something?? FOR EACH ETHERIC LIGHT.
