If you were a pro at PES2011 then i can understand it, otherwise i can't
Because, i'm sure my passing was way better on assisted than on full manual as well as defending and all round play in general. The AI really helps if you play assisted.
I for one didn't play PES2011 extensively so i'm behind when it comes to the 'learning curve' of this game-engine. That could explain it...
Shooting is still incosistent yes, i agree.
I didn't play 2011 at all actually but I've played FIFA the past couple of years and there the full manual setting still feels a lot more manual than when you move the pass assistance slider all the way to 0. I'm not sure about the LT/L2 manual pass trigger, haven't tried it so no idea how that works...
