So to be a smart crafter and very efficient one as well, you would want to work on your gatherers example: Miner-Botanist-Fishing.

Why? Because when you are crafting u of course are going to need mats(Materials) and when u do u are more than likely going to try to look it up on the mb(market board) and its going to be a lot sometimes. You could just get it for free if u had a gatherers class maxed out …. And if u can't get that mat from gathering just have a class/job to 50 to farm

I myself can't say that I have put much effort on crafting/gathering but when I do get back to leveling those I will work on my gathering first …. And yes I know it's boring as hell. Got to do what u got to do….
