I just think it's funny how fucking overpowered Shanks is
Like he lost his dominant arm at 27 years old
I don't even need to get into the chronic pain that comes with losing a limb, or the balancing problems, especially on a surface that's constantly moving or tilting (ship), especially for doing something physically demanding like fighting
He was already on par with the world's greatest swordsman at the time, and then he lost his arm, and then in less than 10 years he not only learned to use his non dominant hand for everything, he got good enough at it to be so strong and such a threat that he was named an Emperor of the Sea along with three other monsters who: a) all had devil's fruits; b) were all much more experienced; c) were all former members of the Rocks Pirates, a group so strong it took Garp AND Roger working together to take them down; and most importantly d) they didn't have the setback of losing an arm and having to train to fight all over again (assuming he wasn't ambidextrous, and even then considering he still wears his sword on his right side, despite that probably making it a bitch to draw quickly, it seems obvious he at least prefered his left hand).
He's also the only one of the original four Emperors left after all the chaos the Worst Generation brought to the New World.
No wonder Buggy has the king of all inferiority complexes, imagine growing up next to that
