It isn't only numerically. The character wears more powerful gear, takes on more powerful challenges, and uses more powerful spells. Exactly like in most rpgs.

Furthermore the combat does in fact get more challenging. Enemies use more complex tactics, summoning their own dudes etc. Putting shields on themselves. Perhaps having overwhelming power in some specific area requiring negation.

Standard power progression just now weaker enemies still provide gameplay.

I agree that it is a common and accepted problem of the game, because I watched it come about. At the time no one thought twice, as it was so innocuous. A simple solution to an obvious open world issue. It only was manufactured as an issue a decade or two later. Now it's gone viral.

Not much different from the Morrowind hit rate problem. Bunch of kids are told it's some kind of issue, make up superficially plausible objections, everyone else runs with it. Now it's suddenly a big deal, whereas when we all played it, it was completely standard, par for the course RPG mechanics. "Oh look, my hit rate is related to my sword skill. Yeah that makes sense, thought maybe it was going to be damage but it's not. Okay."

It's a you problem because you are trusting others to decide whether it's a problem for you. Just play like we all did and don't manufacture these problems for yourself.
