Yes the main quest you get to travel by airship and later on use boats to other areas.
Currently i have Goldsmith, Weaver, Leathersmith, Blacksmith, Carpenter, Armourer and Alchemist that i am working up
Also you can have other classes (jobs) like Miner and Fisher which Miner helps for your crafting classes especially armourer
Simply doing Leves for your crafting nets you good xp and Gil
