Blizzard should have a specialization of jewel crafting that does nothing more than create gems with a ridiculously high vendor value and no other purpose.That would feel thematically appropriate as a route to take the profession.
This all sounds really cool. It seems like we're finally getting deeper profession options. I just hope they make all of them equally viable. Too often, you wind up choosing something you might not like as much simply because it's the most profitable option.
