Adding to this, is the feeling that the players reaction lag to the ball. Whenever the opponent passes or chase the ball, the player who just got 'switched to' seems to lag in response, and feels heavier/laggier when running. I also have the problem where every AI team (no matter which league or teams) seem to ALWAYS favor through-pass (especially overhead through pass) and their passing accuracy is extremely accurate, despite their lack of passing skills. This basically makes every match be the same, on top of the defenders being loose on the attackers and that for whatever reason, nobody on my team would be marking opponent outside of the penalty box so I will never always get the ball back after being punched by the goalkeeper.
I think a gameplay options and/or patch is definitely needed to beef up the AI (both COM and player).
