I've managed to get Blacksmithing 1-600 recently and I believe I've noticed something rather disturbing. So to make the real nice 522 ilvl Blacksmithing gear, normally you're looking at crafting with multiple Haunting Spirits. So, obviously this is going to be a long and complicated process.
Now lets think. On Bladefist-US the cost of ONE haunting spirit is roughly 12000g. For the 522 Plate helm I can make, it requires 8 of these, as well as a few other pretty tough mats to obtain. Lets say you were purchase these materials, as they are very hard to actually farm. If you were going to sell the ilvl 522 gear, I'm relatively sure it would cost more than leveling Blacksmithing 1-600 by itself.
Doesn't that kind of show some kind of an issue here?
