Ok, I understand things much better now. You can pick any 3 of 8 to learn at a given time. Does that mean you have to basically "unlearn" one to make room for another one? Or can you keep your knowledge of them and eventually have all 8 in your repertoire, but only able to work on 3 at once? There are occupations (8 at the moment) and (in addition) there were 2 advanced occupations before server merge (I heard that at a time there was a third one that was maybe removed, or never been available, because of some troubles with aura system).
And, amongst the 8 occupations, you can only pick 3 at a time, but you can master the 8 of them, alternatively.
About the 2 advanced occupations, it's as Daomei wrote.
Be careful about writing occupation or advanced occupation.
