You don't need to do all the fancy stuff to win. I'm full manual, so if I play online or against a local player who has full assisted controls, the most important thing for me is to maintain control and keep my passes clean and crisp. I have beaten assisted players online just by utilizing good passing and patient, careful defending.
In my opinion, a one-button skill move is a HUGE step backward. NHL uses this and its far too simple, so everyone is doing them constantly, and they work too well or not at all, because without the skill stick its only timing, not timing + execution. The skill stick adds move speed and exit direction which is essential, or I wouldnt even touch this game.
