I've seen this same person when he use to concern troll the MHA subreddit before he got the banhammer
Bruh you are giving these manga writers waaaaay too much credit....also I fail to see how adding "spectacle" would detract from the human or more emotional aspect of a series....if Deku punch out a mountain is that going to detract from the "human and emotional" aspects of the series?
Manga writers in general are usually C and D list authors....compare their work to actual novel writer and they look like crap in comparison.
It's not about credit. It's about the type of writer one is.
Some mangaka clearly care a lot about fights. You can see that in how they write fights, powers, and power levels e.g. Dragon Ball or Yu Yu Hakusho. If it's technique you can just look at JJK & HxH. With YYH and HxH, Togashi has shown he can do both raw power level fights & technique/strategy based fights.
For MHA, such things definitely come second to emotions and the likes which Horikoshi always gives precedent in his fights. It does not make Horikoshi more "credible" it just means he's a different type of writer.
(Also I saw your point about spectacle and there is nowhere where I said it would not happen just that it is incredibly hard in the setting. Deku isn't killing any innocent civillians so let's first get that out of the way. Anyway, Horikoshi could always take the fight to a deserted island with mountains and geography to destroy).
Other writers may focus on choreography when writing a fight. They might even write a 10 chapter fight but for MHA even the biggest fights barely clock 3 chapters.
I think the longest fights so far is Gentle and Nagant. And we barely have any fights above 5 chapters.
And even then for the major fights, choreography takes a backseat and for something like Kamino, Horikoshi had All Might throw like 5 punches max. A lot of the weight in Kamino or even Deku vs Muscular and more than half of the fights in this series come from the emotional aspect.
That's where Horikoshi excels while say someone like Gege excels greatly in fight choreography.
Unless Horikoshi suddenly changes his writing style and becomes a meathead the next day, some of these things will remain fantasies.
