I get what you're aiming for, and if that's your vision, you should stick with it while you gather feedback. If multiple players point out the same thing, then it's worth reviewing, but for now, it was just my opinion.
In most cases, when I hit the green bar, it still kept going all the way to the top in gray. It felt like the actual window for the perfect shot is much smaller than what is visually shown.
I just tried the warrior, and what I can tell you is that the enemies attack really fast and the knockback is pretty strong (my lack of skill plays a part here). But it brings me back to my previous point about the character feeling slow or stiff, whereas the enemies don't feel that way.
Sorry if my feedback comes off as super negative, I'm just giving my opinion hoping it helps improve things.
