Well there is more leves for whatever craft class you have in which town has that crafts guild is located.
yes, your point would work assuming everybody in this game were into crafting. as for my take on it i despise it
i think its the biggest waist of time ever, **** i could make a real shirt faster than i could gain levels to make a shirt in game.
only one problem, the only way you can get decently priced gear is to craft it yourself. because to get decent level 30 gear your going to need a crafter that is level 50 in more than one class.
