Sorry to say, but Togashi can maintain that level of consistency solely because he takes breaks, and has long periods of time to think about, and flesh out his characters. I love HxH as much as the next guy, but give Oda or other mangakas months/years long breaks every arc, and they can do the same thing.
The man took one break throughout the entirety of Yu Yu Hakusho's 4 year run, and towards the end of that manga, it became almost unbearable to read, and had one of the worst endings to any series. What do you think HxH's quality would be like if Togashi didn't take the amount of breaks that he does when he got writer fatigued after just 4 years of YYH, and he was still young back then?
