Your ZKK brain can't understand Big mom literally wasted her CoC Haki on Page1, and then Ulti, and she fought Marco and Jinbe (the Shichibukai that you wank), then rooftop and those 2. While Kaido fought 9 Scabbards, Yamato and Luffy in turn. Which is something Ladmirals can't do.
Luffy literally has Shichibukai working for him (Jinbe) and this troll think Shichibukai some shit.
