I've been using a hrap4 for this game ever since it came out, and my performances were not the best. I actually switched to the regular ps4 controller and it felt like a revelation. Either my stick is just defective or it just sucks. I kept messing up with it, i couldnt do combos well at all, I was starting to think that I was getting too old for this shit, but damn.
Playing with the ps4 controller feels like a dream after that.
