I wish Nasu cancelled FGO and then focused on Mahou, Tsukihime, Case Files, and Notes. He's already beaten the concept of heroic spirits and grail wars to death so he needs to move on and explore the other parts of the universe.
It's time we explored the Clocktower, Atlas Academy, Dead Apostles, True Ancestors, Oni, Mixed Bloods, Church Executioners, Types, A Rays, E-Liners, True Magic, Magus Origins and Affinities, Aristoteles etc.
