Oda has put himself in bind by placing that time limit.
No wonder he is rushing these fights. I won't mind if he do so but not when he gave ample panels to useless stuff which were not needed.
But suddenly this time limit would not matter when Luffy fight will come up and oda will drag it for many chapters while other important characters would go around doing garbage stuff.
Oda literally destroying what makes one piece - The SHs for the sake of other useless plots and over emphasis on Luffy
