That is only your assumption that just because the characters are getting stronger that means the drama is thrown out the window already. Are you seeing over the top powers and abilities that would break the story just by existing? because I don't, and the sole exception, Eri, has been addressed, since she can't control her quirk.
plus you are thinking that just because characters increased their abilities that makes all fights pointless because they are pulling DBZ, Bleach, and Naruto levels of "cool just for the sake of being cool" powers when it hasn't even hit that level with most characters. It has shown no matter how strong they get there is a way to counter their powers so the drama and tension of the fights is still intact. In most cases anyway.
And Lastly you are only assuming the endgame of Deku being op when nothing of the sort has happened yet as he is still learning to control the super strength of OFA, the other quirks have not popped out yet. and the ONE TIME he did show his full potential with OFA's strength was with help from Eri and again, she can't do that at the moment at will. Not to mention when we reach that point who's to say there won't be villains that are at AFO's level or stronger. The shonen formula has always introduced new villains as bigger threats than the last, and yes it WILL most likely devolve to the point of being so ridiculous that it simplifies to having the most OP kitten come out on top (who has the biggest stick, so to speak), but we are not at that point yet. You are having those assumptions and feelings prematurely when we are not even there at this point in time nor do we know how it will be handled and written.
Why do I have a bad feeling in the future, I will have a gif of a character leaning forward for an apology as the other character takes time to say, "I'm sorry." Seriously, while it is an assumption, it's not something to disregard.
The series has hardly keep up with everyone to be in the same wavelength. With all due respect, I believe we have officially hit the breaking point of the fanbase and where we may begin to split apart. I am hearing loud noises over 4chan and reddit. I remember thinking I was alone on the non-sense that happened with Overhaul and it turns out I wasn't. I did some digging and apparently a lot of people hated it. The one thing people took great advantage is "explanation." We get explained, but we shouldn't eat everything they give us, no matter if we like the series. It's like Pain's revival. We know he can do it and hell, we know he is capable to revive everyone. The question is, must we? For narrative sake, no. That's Eri. I can another 30 minutes why that arc harmed the series. Even the announcement for Season 4 got people only talking about the reactions of fans, more so than the content itself.
Optimistic or not, the writing in the past hasn't favored any character that isn't Shouto, Bakugou, or Deku. If they were, I would like to know when. School activities don't count. Because of experience, there's no way I would believe the students are up to the same wavelength. Even in this arc, barely anyone got developed. Do you honestly want me to remain hopeful? Do you believe everyone will remain hopeful? I know Naruto may have scarred everyone and while this series isn't there yet, it's garnering the elements that will be its downfall. I'm sorry for being part of the fanbase, because I can imagine people want me out for having an opinion outside of "praise the sun."
Once again, experience has led to this feeling. You may think Kohei's writing is top notch, I think it's mixed. If this revelation was to happen immediately after Hideout Raid Arc, I would have some confidence. Plus, it's earlier on before we establish the power gap is growing. However, after many hiccups and head scratching moments, I have the rights to feel worried and more. Plus, there's more takeaway from this chapter than future assumptions. Of course, future villains will always be stronger, but many of characters are being left behind already, development and action. I don't remember the last the class ever taken on a boss level character or even sub-boss. Can I be wrong? Yes. Can you be wrong? Yes. There's no denying that there's a lot to fear and understandably so. It's only matter if we feared nothing or scream for the doomsday.
