I've read books, yes. But I'll say it again:
I also love when something is thoroughly explained, that is definitely one of the most important things for a story. But Togashi seems to be focused on powerscaling a lot because even when he wrote a one piece panel for Oda it was literally just Kaidou talking about how his subordinates have good Haki and how Luffy might also have good haki. It's not necessary, we aren't that dumb, simply show them using Haki in a fight, it's that easy, there's no need for a bunch of text about Haki, what it is, who has it, and what you think about it, that's too much. Just talk about Luffy and his Haki, and what you're going to do about him.
