I personally don't have much interest in a lot of difficulty in games anymore, with my limited game time I would much rather play a chill game then bang my head against the wall getting frustrated with difficult combat/puzzles since I'm generally more interested in exploration and story.
That said, I do feel like the difficulty in BoTW/TotK is almost entirely frontloaded. Early game combat is brutal, your weapons are super weak and break all the time, you don't have many healing items and many enemies can kill you in one or two hits. Once you find places to consistently get decent weapons and fusing materials and healing items and armor, suddenly the game becomes a LOT easier and you don't really have to bother dodging attacks and can just tank them.
This early game difficulty doesn't need any increase, at most maybe give enemies some new moves. Many enemies already kill in one hit so increased damage doesn't really effect anything other than push the combat difficulty tipping point out, and increasing their health is just going to make combat a lot more tedious as it's going to be hard to carry enough weapons to do anything. Even on regular difficulty the best approach is just to avoid combat early on and increasing difficulty here is just going to further reinforce this approach and make exploration even more tedious.
If I was going to tweak difficulty to reduce being overpowered in the endgame, it would probably be around how armor protection is calculated (percentage rather than flat damage reduction?) rather than just buffing enemy attacks, and also maybe putting limits on healing items like on how often they can be used (i.e. no eating during combat, can only drink health potions with a cooldown).
