I don't know why I should be responding to a sad ZKKer in the first place but:
Every swordsman fights differently... but according to you Shanks is a regular swordsman.
If everyone fights differently with a sword what makes the standard? What defines "regular swordsman"? Marine fodder with fodder swords are "regular" swordsmans just like ACoA specialists Denjiro and Ashura?
Lest we forget that I didn't even imply that an "unique combat style" is exclusive to Shanks. But when you have the author posing a question to the audience unprompted, you really expect that the answer is just "he's just like Kaido but imbuing a sword with ACoC instead of a club"?
If that's so: lmao.
Funny how yall are turning back to ZKK at every chance you get, even if it has nothing to do with the discussion...

Yes, Shanks is a regular swordsman. That doesnt stop him from fighting differently like all other swordsmen do.
Yes, marine fodders are same regular swordsmen as Denjiro and Ashura, they got nothing except a sword and haki.
Just like Shanks.
Kaku is a swordsman but how does he fight? Mihawk is a swordsman but how does he fight? Fujitora is a swordsman but how does he fight? Shiki was a swordsman but how does he fight? Ryuma was a swordsman but how does he fight? Rocks was a swordsman but how does he fight? Every swordsman fights in a different way, nothing new about Shanks have a different way compared to others because others are different compared to Shanks as well.
If you thought Oda would draw every major swordsman fight the same way, you didnt pay attention so far.
What yall are hoping for is something entirely else, something that would make Shanks into a non-swordsman.
