Noticed that having a level 100 craft really adds a lot of value to an account... but im not sure why. It has always seemed to me that, while you can craft expensive stuff, that is counterbalanced by the cost of the materials. So you end up making minimal profit at best. Unless you get a lucky HQ, which is rare. Can you make enough gil with a 100 craft to not have to buy gil?

What do you guys think?
