Alone the fact that Whitebeard don´t use Advanced CoA(im sure he have it), Gura power and his awakened version just show that Roger was either in casual mod without using his true power, yet alone the make such a big impact who even create tsunamis, it just amazing and I can´t imagine how op they would be if they would fought all out with using their strongest attack.
We see in previous arc the top battle of the High tiers(Katakuri vs Luffy) and their strongest attacks(G4 Snakeman) aren´t even equal to casual attacks of Whitebeard and Roger, the gap is insane huge and it shows again that Luffy has a hard path to reach that lvl.
The animals on the island know that a nature disaster gonna happen soon. What make me amazed is how easily Roger deal with Oden, let say Oden was a low top tier, seeing how Roger easily handle him with one strike while don´t even use a a powerful attack(casual named attack as Luffy would using Gomu Gomu no pistol or something) shows how op Roger and Primebeard was. Happy that Oda show again that the clash two chapter ago with Whitebeard and Oden was just a short clash, Whitebeard is still leagues above him.
And this Oden gonna scare Kaido soon.
