So, could you spam light attack and Quen and power through 95% of the content? Yeah. But it wouldn't surprise me that if you're not using all the tools that you don't find the combat very interesting. It has its flaws, though as a real time action RPG system I think it does better than most outside of like Dragon's Dogma and Dark Souls. It has far more interesting melee combat than Horizon as well, which I understand is not the focus of Horizon but I simply have very little interest in bow combat.
I have never agreed with the argument that if the game gives you the option to do something boring to succeed the most then it's your fault for picking it.
I am most immersed in a game when I am doing everything in my power to succeed at it. I cannot start putting arbitrary restraints on myself mid-combat to make it more difficult. It goes against every instinct. It also pisses me off that I'm essentially taking on the role of game designer by picking and choosing mechanics to use and ignore to maximise enjoyability when I thought I'd paid someone else to do that for me.
Anyway, I never minded the controls, I just hated that I never got a challenge even on hardest difficulty. And i'm usually awful at combat in these kinds of games.
