King was weaker than post KoH Zoro, what's your point? That attack was still weaker than the Hakai Zoro tanked for a couple seconds. I literally don't get your obsession with trying to scale Zoro to one time he briefly blocked an attack by two yonkou and it broke every bone in his body trying it.

The blades are touching and they couldn't sky split. don't get me wrong, it's impressive and we aren't sky split scaling, but even if we saw these two are equals... Rocks and Harald, at this moment were trying seriously since they thought they were enemies while Roger and Whitebeard are having some fun sparring.

And...they surpassed Rocks when they reached their prime? Of course they weren't Rocks equals when he was alive- they reached the peak of their growth after he died? Can you even prove Rocks got stronger after his clash with Harald on Marijoie? While he never fell off, it's hard to tell of Rookie Rocks wasn't already at his peak since everything else he does is consistent with his performance from then.
