That setbacks make things fair, and situational matchup is also good. I really don't like most isekai stories that every single skill that they have is straight out full overpowered benefits with minimum or no demerits. Playing out the demerits strategically is the fun of fantasy battle to me (if they intended to make this a rather large portion of the story), and imo braindead OP MC is fine if the author able to craft a good story with depth for that character, so we know the focus is not simply flexing OPness on every chance they get.
That would be a solution, though I'm hoping the OP battle that will be produced is not something like:
'MC's punch can shatter a meteor!'
'but the opponent can clap to shatter a planet!'
'MC then powered up so he can sneeze to destroy galaxy!'
type of shit.
So am i the only one who is in awed in how dynamtic their fight is? It's not just a bunch of attacks flying nor a bunch of zigzagging lines to demonstrate how fast they are, the fact that it's the background that gets blurred coupled with their every changing movements is such a fresh take for me.
