Bro you're literally trolling — Whitebeard didn't get a heart attack just because he couldn't keep up with the Admirals, he got it because he removed his life support and was on his last legs the second he stepped onto MF 😭😭
Of course he got bullied by Kizaru, how tf does he keep up with a lightspeed man without CoO and no CoC to protect himself to boot 😭
I don't think it's being acknowledged exactly how much weaker WB was on MF to his regular old self. No CoC and no CoO is absolutely insane — he was complete buttcheeks compared to even his regular old self and still managed to outperform Old Garp, and you wanna tell me Garp is magically his equal or superior in their prime because he got some good portrayal when they were younger?
Nah man.
