that would be awesome, but i think Yamcha still wins due to him being more skilled in H2H combat, i mean don't get me wrong Madara is pretty good but Yamcha received a training for h2h and h2h only, while madara didn't train that much in h2h category.Yes, Yamcha would certainly have a huge skill factor since he trained with master Roshi and then Kami for a year; but we can't exclude Madara altogether. He did rise up to become the head of his clan who are renowned for their battle prowess, and he has shown remarkable skills using weapons. And even if that remains questionable, he did also completely wreck a large portion of the shinobi alliance in h2h alone while they were all ganging up on him.but he had a huge speed advantage, in tha naruto verse, you have more chakra means you're stronger, faster and more durable, so Madara was really relying on his power rather than his skills, and that's why Yamcha have an advantage in this particular situation. That's a bit of double standard though, wouldn't you say? Ki is essential to DB characters because it heavily increases all of their stats like you just mentioned. Without Ki, the cast would only be peak humans with extreme martial arts skills.
Also, saying that they don't rely on skill in naruto is bit of a stretch considering that it had more planning and strategy in fights than DB has had.
1-Strategy doesn't work in H2H combat, like in the tournements, you don't see master roshi or Goku planing what to do next they improvise and adapt to the situation.
2-this is equalization, they have the same speed durability and strength so it's just skills, the best one in H2H combat wins, which in this case Yamcha for having better close combat skills, but when it comes to like war and ninja stuff Madara hands down because he's a better strategist.
It isn't simply strategy alone; it's necessary to also have the skill to pull the strategy off. And I'm not saying that Yamcha is inferior in h2h, but rather that you aren't giving madara enough credit. Refer to the fight between him and he shinobi alliance; that alone would be a testament to the raw skill madara possesses.
