That's disappointing to hear. I was excited at all the different things you can do this in this game, and to hear some of them aren't worth the time....
It depends what you want out of the crafting jobs. If you want to become a gillionaire then you'll probably be disappointed by most of the crafting jobs and all of the gathering jobs unless you're prepared to put hundreds of hours into them. If you just want to be self-sufficient and to not waste your Gil then you'll be quite pleased.
