I knew the "if you farm everything you can name the price" would come up and my only answer is this. If market price for materials is 200,000 gil and you get everything free by farming then why not earn 250,000 gil on an hq and let the mat buyers make their 50k profit too.

I almost never do anything outside of my FC because people are crazy. Off topic I had an off tank in Ifrit HM that didn't know what ability was stun on his pld. Some crafters are out of their minds much like him.
