Yes, I know this is a secondary profession, but the RNG involved is absolutely atrocious. After crafting my 5th "Delicate Music Box" and still getting numerous Fossil sites, even after having solved all of them, I am wondering what on earth Blizzard was thinking with this profession.
There was a blue post on this a long time ago saying it was something they were looking to implement, Then Cata was heralded and it got put on the backburner I presume so nothing has been heard for a long time.
