Powers & Abilities Would Shanks have the same fighting style as Roger ?
Well if it's so, i think Oda is just planning to obscure things out even more in order to prolong strongest swordsman vs CoC master powerlevel debate. I personally dont like this, Oda constantly pit Shanks vs Mihawk and Yonkou vs WSS, title vs "not traditional techniques" etc. There're ways to present powerlevel hierarchy, but making it obscure is not good imo.
I’m not saying he isn’t, but we don’t know either fighting style of the three Ray, Roger and Shanks to really confirm how he uses his sword in a fight cuz Brook’s swordsman is the same style as someone like Zoro so among swordsman obviously they have variety of styles which means we can’t really tell how Shanks fight with his sword even if we say he learnt from Ray or Roger cuz both are a mystery to us.
I have no facts and no arguments either, but it is only an impression since they resemble their personality a little, that are free, and that no one hurts their mate, and they are both left-handed. Shanks may have been inspired by Roger and his fighting style; they even seem to use the same sword.
I also don't think they are just ordinary swordsmen, they didn't even bother to make the sword permanently black, even having CoA top tier. They must have other powers that channel their power, my guess would be both having the unique power of channeling CoC as a form of atomic energy that would work similar to Fujitora's ability; Oda when talking about Shanks on SBS put the question: '' How does Shanks really fight?''
Probably Shanks has the strongest CoC shown so far, so I don't find it impossible for him to have a unique power that only Roger was able to use. And Shanks managed to arouse him when he lost his arm, causing him to gain a PU for he be stronger and become a yonkou in the following years.
