It's funny how Big Mom's amnesia is not considered as bad writing but defeating Kaido in 1v1 (something that mean character is created to do) is.
I'm reading shonen manga for 1v1 fights and not for cowards who jump on the stronger guy cuz they don't have the balls to face him alone, You guys can team up with your friends against the bigger guy since all of you are bunch of cowards but one piece is about bravery, achieving the impossible, breaking the limits etc. And I expected a great fight between Luffy and Kaido.
People think that Luffy will defeat Kiado in his current power level and this is why 1v1 seems impossible, but Luffy will not be able to defeat Kaido in his current power level even if entire alliance attacks Kaido together, Luffy will become more powerful and 1v1 against Kaido is the final round anyway.
Team fights take away form character achievements, defeating Kaido in team fight is the same thing as not defeating Kaido in first place, only bad guys team up against the stronger guy like Blackbeard and Akainu did, Luffy is not a bad guy and he already said that he's against sneaky tricks.
