Also for the Lore spells, maybe we can have thematically appropriate bosses drop those spellements (eg, Queen Calypso in Celestia, one of the Draconians for Keeper of the Flame, etc.) Just having it for those three randos in Mooshu feels unfair.
I agree with this. The spellements by rank should match the final world of the rank of the spell or have to do with the origin of the spell. I saw a video awhile ago with Blaze LifeHammer. He suggested a pack that offers spellements by the school. Such as jewels per school. Both of these ideas I could see happening.
I definitely agree with making a lot of the Spellements easier to get. In fact, in one of my posts over on Central I even called for letting players upgrade their 1-pip spells via Spellements before they are even done with Unicorn Way. End World bosses would still fit in well in this sort of situation by being able to drop Spellements of every school rather than just your own!
