I don't know how you can be an honest person and deny the fact that relegating Mihawk to being Zolo's Sensei has been nothing but bad for his character.
Imagine if instead of half of early Naruto just being Itachi negging characters, we just got occasional panels of him worrying about being chased by the Anbu and talking about how Sasuke beating him was less hard than becoming Hokage.
It's how you end up with big panels like this...with Mihawk being absent
