It's been asked a lot of times before. They just need to remove the class item and keep the lore. You hold the crystal with you in spirit and reveal it in cutscenes wherever it's necessary but you wouldn't need to actually equip it. It would save on a lot of inventory space so that it can be used for other things since they budget every bit for every character. Ah, but you ask "what about scholar/summoner"? Don't worry, I have a solution for that as well. When you swap over to said job using the equipment, a toggle button will show up on your avatar. You'll be able to toggle between Scholar/Summoner and save that plate exactly as-is. This setting is saved on your computer like the rest of your plates. It's a simple and elegant solution and as for the soul crystal that is given to you, they will just need to go to the base class quest and remove said item and adjust any quest that requires you to equip the soul crystal as necessary. It wouldn't be much work and your character would still operate as-if it is of a certain class. No need to deal with hardcoded anything.
