I mentioned earlier that they do feel like playing with a kid that always has to one up you, for the sake of balance there are a few bosses I'd personally nerf, not be HP but by one or 2 moves/combos and maybe tone their aggressiveness down a bit
A perfect example is Melenia, healing on hits is fine as a mechanic on a boss, but not a boss that is always super fast and hard to deal with anyway, it's just overkill.
Another is a dragon I saw on a stream yesterday, its at the end of the Fia quest, it constantly spams this red lightning at you, so you can only do 1 or 2 hits before rolling as if you don't you get massive damage against you, get knocked over and the Dragon will then attack you again, getting your bearings after that is rough
You're right though, you do learn to play it their way, but you should be able to play it yours, how many people in this OT have asked the same question "Can you play this game completely Melee?" and my answer is YES, I did it myself, but its harder than Ranged builds
