I really hope Elbaph will only be about 40-60 chapters long. The fact that people are saying it will surpass Dressrosa in length is ridiculous. Where does this sentiment come from? We don't need 100+ chapter arcs to tell a meaningful or impactful story. Marineford is only 30 chapters long, yet it's a lot of people's favorite arc. To me, it shows that previous arcs, such as Egghead or Wano, have completely warped people's perception on how many chapters a One Piece arc should have. Thankfully the pacing for Elbaph has been perfect so far.
HOWEVER: If the arc actually ends up being 70+ chapters long, I will kneel and apologize to everyone.
