I do enjoy the supernatural drama, it seems like a fun idea, but I really don't see why spellcasters and fae would hate each other, and I'd love something different instead of a rehash of the vampire-werewolves thing. Maybe they actually work together, with complementary powers / ressources that they can provide each other. Quite frankly, when spellcasters came out, I was hoping magic would be a subsystem any sim could learn, and that "born spellcasters" would be fairies, giving them quicker scaling to their magic ability and some unique abilities and spells. So having them be rivals instead would feel weird to me.
