The problem with D-Pad, at least in current PES games, is that favours Speed Merchant abusers. It's so much easier to pull those abrupt turns with only 8 directions.
for me the biggest problem is lack of movement depth. since i had this thought in mind all the football games feel so outdated.
think about how you currently dribble in football games, because you can only move a set distance (jog>sprint, that is it) the defender knows at what distance he can or cannot tackle you. this is why in games the 'right' way to dribble to do ridiculous 90degree turns or turn backwards altogether and shimmy and shimmy until you lose your marker.
with depth of movement you could gently push the analogue stick forward and actually square off face-to-face with the defender and push him backwards. this is not something you can currently do and until it is implemented we'll keep seeing this silly "shimmy everywhere until your oppenent presses the wrong button" technique of dribbling
