Better Computer AI, defensively and offensively. That's a common goal I would assume for the Konami team anyway, improve the gameplay basically. For example, I played a world cup level 5 with china.
Through all my games, I noticed that the computer, on offense, did not take advantage of the huge difference in skill between their teams and mine i.e. speed, stamina, ball control, shooting, the works basically. It was quite bothersome to say the least, I know bad teams can have good days, but every day! Naw, that just can't be! The AI just doesn't exploit my team's weaknesses. Once, maybe twice I "might" have seen this being done, in a game with Senegal, towards the last 15 or so mintues, my chinese team was up 2-0, Senegal finally really exploited my lack of speed in two plays, which they scored both times!
The defenive AI just needs to be smarter it seems. They bite too easily on cuts.It needs to be more agressive, yet not reckless! Especially around the PK box, the computer lets you dribble around way too easily at times! The defensive flaw is pretty minor though copared to it's offensive AI.
For your team's offensive AI, this definitely could use some work in specific situations. Players never check to, trying to make themselves open for YOU in case you have no current options. Your AI players are just making runs toward goal, never to support you. Also, once your teammates have made runs into the box, they suddenly become somewhat stagnent. It's as if they are forcing you to just cross the ball in, in doesn't recognize that you are holding the ball trying to look for someone to open up for a pass. No one to reset the offense, just you running round outside the box hoping that someone will decide to make make a run out of the box and check to so that you can start up and create some offense.
More realistic reffing. Sometimes you are about to cross the ball into the box, but to do so, you need one extra sprint to get into some open space to cross the ball around the defender, but once the ball goes ahead, the computer grabs onto you, impeding the your needed speed to get to the ball, hence the ball goes out for a goal kick!I would like a foul called or for me to be able to do the same! If not that, an animation where your player turns around hitting the defender's arm off of you and then looking to the ref for a call! Something you know, stating that something went wrong there.The last man foul I rarely seen call, atleast on behalf of the computer. I don't foul much at all. I probably might get at most, between 5-8 yellow cards a SEASON! Throw in probably 1-2 red cards as well! Anyway, that's all I can think about for now. WE6FE is a great game though, no doubt!
