This.
Do not forget that Ace was not just strong but "i can fight Aokiji on equal terms after i have been in prison"- strong for f*** sake.
And i am damn sure it was not just because of fire > ice.
Uhh…why. Fire attack vs. ice attack=negation of attacks. It wasn't complicated, he didn't hurt aokiji and vice versa.
What's still hauntingly confusing to me is why Kuzan didn't just punch him with some haki. would have done such a better job in that case
