Honestly this is what I like about JoJo, the fights rarely are about overpowering your opponent but rather outsmarting them, that even a crappy power can win the fight if used correctly.

And it's been like that since Phantom Blood, too!

>Vampires' only weakness is sunlight
>Hamon is the power of sunlight coursing through your blood
>Punching Dio doesn't work because he can vaporise blood, freezing you on contact
>The frozen limbs can't conduct Hamon because there's no blood in them(?)
>Use a sword on Dio, charged with Hamon
>He freezes it
>Set the sword on fire so he can't freeze it
>Cuts him in half, he's fine, he breaks the sword
>Charge fist with Hamon
>Set that on fire, too, so he can't freeze it
>Punch him off a cliff
>As his body disintegrates from Hamon, his disembodied head shoots laser beams at you, which had never been shown before, not even once
