[3.0] Craftsmanship and Control bonus parameters will be added to Souls of the Crafte

[Kakure]

So now, instead of people making gil off of it, I'm avoiding it entirely or avoiding paying for it with a friend.

You're missing the point. Exchange is axiomatically good. Bartering with your friend is no less a form of economic exchange than buying stuff from a stranger. Looking for a more favorable arrangement and opting not to buy something when the price exceeds its value does not make economics wrong; that's the mechanism by which the system works.

One of the things I enjoyed about 2.x was the possibility of becoming self sufficient on one character, if I were to put enough effort into maxing out/gearing all the classes.

I enjoy being completely self-sufficient as well. I would also enjoy it if black mages were made invincible. What players enjoy is not always the same as what's good for the game.
