There has long been complaint from crafters that their skill is useless. To craft anything worthwhile you need not just high level of appropriate crafting, which is tedious, expensive and time consuming to develop, but also mats that drop in instances only.
That was addressed somewhat - the stones, nails, fibers, etc, now drops in mysterious bags a lot more; but the gear is still not all that good. It tends to be decent, but not quite up to par with instance gear, so it is not used much. So, crafters once again feel useless.
At the same time, you can't make the gear too good. People need incentive to run instances, and getting second rate gear from drops would reduce that incentive if people can use better gear from crafting.
So, how do you encourage both instance running and crafting? What about creating a combined gear system? You can craft good gear as you do now. You can get great gear from drops. And to get the best gear, you need both.
If a crafter can take an instance piece of gear and enhance it in a way that only crafter can, that would encourage people not to ignore half of game gearing system.
The game already tried this - you get a whole bunch of recipes that take Standard Sharp Sword of Slicing and then enhance it to become Superior Sharp Sword of Slicing. Problem is that the final product, while better, is not all that great. So, why not take it up a notch? Take, as component, the best instance gear and make it the best game gear.

Oh, and people who have more than 3 classes are clinically insane.
