I'm currently a Jewelcrafter and a Engineer, but with 4.2 coming and little being added to Engineering I am considering swapping it for Blacksmithing. The main reason I've been thinking of switching is for the crafted items that are being released in 4.2. I have a boat load of Chaos Orbs saved up and if I could put them to good use instead of paying for another's I would be happy. Basically, I just wanted to get some opinions.
