Jobs <trueself> quest

So I had a dream last night idk why i had a dream about ffxiv its kinda dumb that i did But here is an idea what to do with jobs in future.

Learning from itself basically and how this works is lets say your black mage or reaper both drawing power from void, so what is the perfect way for them to master their craft, its simple they learn from the void itself the very thing they draw power from, the crystal talks to them and commands them to leave for the 13th where they will learn and gain mastery over their abilities by learning from the void itself no npcs nothing expect the job crystal giving them quest. Dragoons would be sent to an elder dragon or a dragons den to gain mastery, Whm idk either something holy or elementals like they originally where in arr. and so forth.

We could give each job their unique zone where they stay to learn mastery over their jobs, This could be extremely fun for example summoner would just have a island where priest of each beast tribe stays where they learn the correct way to summon them, like all of them did at the end of endwalker.
