I had an idea; I don't know if anybody else has thought about it. Please concur if you have. We trade in Exotic Cyphers for one Ascendant shard, or at least a set amount of Enhancement Prisms, if you think that would make Shards too easily attained. The reason being, I never use it. The exotic pool from Xur has become stale, to say the least. So I just always have a cipher in my inventory. I think it would justify doing the cipher quests again. Otherwise, I don't see any reason to pursue the Exotic Cipher. Please tell me your thoughts.
