Cooking is making a come back as I see, but it won't make you the big bucks Leather or weaving would make you.

Also, I offer you some good advice, go for big exp bonuses in crafting, can save you money on materials when leveling.

What do I mean in this? The higher your quality, the bigger your exp bonus. This can mean bonuses like 150% to maybe 350% exp bonus.

But if you spam careful synth, you'll never make it to completion, so the easiest way to maximize exp would be to use rapid at least once and followed by one standard synth(if both of those succeed) you'll want to then start doing those careful to build up quality. Also, in your head I'd say build a average "How much durability you use in a snyth" and you'll build yourself a leveling machine.

Or you know... spam standard, but that's boring~
