...so how do new players learn anything?

Anyways, anyone have recommendations on best method for leveling gathering and crafting classes?

War and Magic are pretty straight forward, Hunting Log, FATES, Leves

Crafting an item for the first time has an XP boost, I'm not sure if crafting Leves are of any use?

Gathering? Is it just a matter of grinding, or are there ways to level quicker?
