Yes it really sound really really really ridiculous to say Roger with his supreme blade + haki is stronger than WB who also have supreme blade + strong haki + top tier DF that could destroy the world.
Ask any ppl who say Roger > WB, what's there reason. They can only give you common answer "Because he the PK" nothing more nothing less. Which lame reasons
They have practically nothing to show.
But Oda already portrayed WB as WSM so it was clear to me
Yes, not having any sort of broken DF, but you can still be on same ground as those, with your haki and individual strength and skills But.....
Luffy peak ceiling is not be on same lvl as Roger, WB, Kaido, EOS BB. He is set to surpass all of them.
If there exists any creative way of using Rubber fruit that could make you surpass than all those inordinary monster. That will be beyond ridiculous and nonsense. Nobody could do it without adding some broken abilities to it.
This why i hate this development but at the same time it is the only that will make sense.
There's no way a character is going to be strongest of all without having some sort of broken abilities.
That's shonen troupe.
