I'm probably going to sound like VampLena with this, but I can't see how you guys find normal/hard mode too easy, especially at the end.
The final fight kicks your butt regardless of what difficulty you're on, I've noticed. Is that too easy? Should they all one shot you regardless of your level?
And with regular fighting/"boss" fights, those are too easy? Do you really think it would be fun to run into a group of two enemies and die a hundred times until you find the perfect strategy to beat them, then repeat those steps on each and every other enemy spawn in the game? Dunno about you all, but that doesn't sound fun to me.
The difficulty is fine to me. You need to upgrade your potions every few levels in order to keep up with the increase in HP/damage. Being one shotted unless you know exactly where to stand, when to attack, when to dodge, and one little misclick/mistake gets you killed is not fun, it's annoying.
Games like these need a mixture of normal difficulty, which I guess you guys call "mindless button mashing" and harder boss fights. You can not make the whole game super insanely difficult or 90% of the player base quits out of frustration. It's a shame this game doesn't allow mods, because that way the people who want insane challenges (and what is an insane challenge anyway, when after you die a hundred times you get the hang of it and it becomes "too easy"?) can mod scary nightmare modes into the game where you die in one hit regardless of unavoidable magic/projectile weapons.
Just my 2cents. I like the difficulty the way it is...The only thing I'd change is the final battle and make it more manageable than "Hope you have a ton of greater restoration potions you can spam"
