At this point, crafting is a money-losing proposition, even at high levels. I got cooking to 69, and (especially now that the Jeuno tax is in every AH), I can't make any money; AH price for crafted foods is lower than the price of the ingredients. The only way to make any money is with HQ synths, and I don't make enough HQ to make it worthwhile; If I synth Chiefkabobs, I eat them myself.
