I have a decent number of wizards who have learned a lore spell outside of their school, and these spells never get used on those wizards. I think an NPC like Lincoln in Ravenwood, or other system, where players could spend either a low amount of crowns or a high amount of gold to "Un-learn" a lore spell and turn the spell back into 35 Spellements that could be transferred to a different wizard would be a great addition to the game.
It helps veteran wizards who may have learned a "useless" spell from farming Loremaster or helping a lower level wizard farm for a spell (like catch of the day) get something out of the time and effort they spent farming before now that there's an entirely new system in place.
And on the topic of Spellements, can the categories that exist in the reagents tab in one's backpack please be added to the shared bank screen? This would make sharing spellements through the shared bank or finding the exact reagent a lot easier and be a great quality of life update.
