I thought about this but it was a different idea all together.

You know how we go from gladiator with gladiator skills then Paladin with paladin skills but retain are level so it would be something like this.

Gladiator > Paladin > Whatever job SE chooses after the class but you return to level 1 and have all new skill sets when putting on job change crystal.

Now if you put back on Paladin crystal you have all old skills and keep your level but the new job would be fresh start anyways that was my idea long time ago.

It was going off the promotion system they had on shining force where you reach max level promote and keep some stats but return to lvl 1

It would also help with cluttered skills if we had a whole new skill set.
