Another idea for the implementation of higher level crafted gear would be to include crafting "job" classes obtainable by equipping a crystal earned by getting a warrior class to lv.50.

While making the specific classes recipes appear, it could also raise the crafters stats and restrict it's cross-class skills thus raising the difficulty bar in getting high-quality results.

'with untradable, unsellable results this would create quite a challenge for players that would otherwise only log on once a week to run through coil.
