I think I don't understand what you mean by 'I played like crap last night.' When I play like crap, I drop multiple combos, fail to react to stuff I think I should have, ect. All of those things can be rectified by going into training mode (or watching the replay) and grinding those situations out, confirming the timings and things like that. No matter how much practice you have, you are still gonna need to go back and refresh yourself time to time. After all, if you fucked up, then there is something you can do to not fuck up the next time.
