I usually don't like to generalize but, here, I'm pretty sure most people complaining about the combat being "unresponsive", "shallow", "sloppy", and similar adjectives either prefer button mashy games, really haven't learned to play the game, or don't like to think about their games. The Witcher 3's combat requires far more tactics than many of those other games you listed simply because it's tuned to commit you to actions: actions take time to perform and you can't instantaneously interrupt it, thus you will be punished for wading in thinking you can just spam some buttons. Basically, it sounds like you are probably getting interrupted a bunch OR you are being so careful that you are playing in a very boring way, both because you aren't positioning well and you're not using all of the skills and items available to you.
