Imo, Egghead is still an 8, for at least payoff potential. I dig the scenes out of the arc, but it needs to start addressing its main points:
- Traitor
- Kuma's flashback
- The eventual point of CP0
- Vegapunk's history with Bakkin/Weevil/Rocks
- Most importantly: Kizaru/Saturn and the Marine Assault on Egghead
