I gave up crafting and so did my roomie who is 50s across the board in crafts. You make more gil by selling your mats anyway and why waste the time and money leveling and gearing a crafter job that's useless anyway.

The actual crafting I find fun and my roomie absolutely loved but the lack of need, well, why bother? If you do want a crafted item, wait a couple days until everyone has undercut everyone else to the point that million gil piece of gear is selling for 50k. Doesn't take that long
