It's funny to me that you can pick any shounen battle manga and compare it to One Piece and the execution in fights are clearly better handled. Oda created a battle shounen with over 1000+ chapters and still doesn't know how to handle fights instead it has gotten worse throughout the years. For someone who claimed that he doesn't like drawing fights, he sure does draw fights a lot.

First thing Oda needs to learn is how to have a legitimate reason for your main character to defeat the main antagonist of your story. Here you see Togashi creating the cause of defeating Pitou due to Kite's death. Or Kurapika defeating Uvogin due to the spiders destroying Kurapika's village. Why again does Kaido need to be defeated? No one knows yet because Oda refuses to tell us.
-------------------------------------------------------------------------------------------------------------------------------------------------------
Next step of writing shounen 101 is that when you spend over 30 chapters on your main character training, you would expect that the training will pay off. You see how one event follows the other in HxH i.e Gon and Kurapika trained in Zetsu, Nen, etc which were crucial in defeating their opponents. You see how they used the power systems that they trained in to defeat their opponents? No bullshit power ups that have nothing to do with what they trained in? Whereas in One Piece Luffy trains for 30 chapters and then gets two new power ups that have nothing to do with the training. Drawing shounen fights isn't rocket science. When you write a training arc, make sure you don't waste the reader's time.
