EoS BB (All DF)> Rogers
EoS Luffy(ACoC +DF)>Rogers
Why are you crying now. First of all, Blackbeard has 2 top tier fruits, will possibly get a third one. He also has Haki on top of his fruits. Luffy, apart from his fruit also has maxed out all of his Hakis, including adv.CoC. And Luffy will have to beat Blackbeard mostly with Haki, due to the Yami fruit locking his DF.
I love how people use characters who have both DF and adv.CoC to prove DF > adv.CoC. Doesn't make sense at all.
In fact, Prime WS was said to be stronger than Roger.
The VCs said that BB obtained the title "well before the great age of pirates"= we'll before Roger's death.
Yes, due to WB's individual strength and the said ability to destroy the world. Doesn't mean Oda himself in the narration said that Whitebeard is the equal of "even Roger". Not "stronger even than Roger" but the "equal of even Roger".
Also, Oda's direct statement > Databooks.
But yeah, continue with the cope Boys.
