because his durability is not entirely insignificant, its still part of his arsenal but not the major one
Scabbards already bypassed his durability, Oda won't just make Supernovas do the same shit scabbards have already done against Kaido then just defeat him
hence the problem is gonna be how to kill him, Luffy will try damaging him from the inside, Law will use his hax, the rest will try some crazy stuff as well
beside its already obvious how Oda will narrate this fight, his relying on shock value and trying to mislead the readers
Scabbards do some crazy shit, then Kaido overcome
Supernova do even more crazier attacks, then Kaido overcome
