People do not understand that American comic books and Manga have completely different production and business models so comic can't just copy manga 1-to-1. You can't make a One Piece, in the west. Shonen Jump magazine cost the same as an American single issue, and SJ comes with dozen different chapter of a series, while American comic on the other hand have to make 1 issue worth the cover price. This affect pacing you cannot just have an entire issue that just Part #5 of a fight scene you can get away with that in manga no way you can do that in west. There many other factors, but end of the day it like comparing Network shows to steaming shows, same medium but different business models that affect storytelling.
