All this talk about dribbling, fair enough, I guess, but how often do you see someone pull a Marseille move in real football? And even Messi doesn't skin 5 defenders in every game. Sometimes (like in the away leg against Liverpool) he doesn't do jack shit at all, simply because he is human and has his ups and downs.
Personally, I'd rather have them focus on the more fundamental things like the passing of the AI, which is so painfully robotic and "perfect", we've pointed it out many times. Headers are another aspect I'd like them to fix. I can't remember when last I conceded an AI-goal from a header and for humans it has become so difficult and unrewarding I am not even trying anymore. On corners I've switched to short corner tactics because regular corners will be cleared anyway by whichever team you play against, even by one with midget CBs. Goalies: another thing. They are incompetent in many situations but in others, they pull ninja moves which feel impossible, both physically and contextually. On penalties they jump farther than the goal post, for crying out loud. Shots from outside the box: how many have you scored in hundreds of games? Stamina system, fouls, refs, proper advantage rule, Most of all: different playing styles per team based on context (Huddersfield will not play 4-3-3 when they are away at Etihad sitting on 18th)... these and more would be higher up on my fix list.
