When I craft i craft to make money not to just level. I make something and then sell it. then with the money I buy what i need to craft another item then I sell that. Made over a couple mill just doing that and got a good start in GIL to buy gear for myself that i need. People to much in a rush to reach max level so they can sell stuff at 1 mill per item and get rich lol.

The biggest problem in crafting that i can see is trying to find an item you need in market to create it as people are only grinding off one item to level and not selling needed mats for other crafters. Then because of this everyone is leveling every crafting job out there to make up for this lack of materials that they are not getting easily. crafting relays on tomany other crafters to make one item. You will notice this alot as a Armor also needing almost every crafter to make a peice of armor.
