Gameplay problems (Bad AI)

TheAI really needs to be better in 12. Sometimes players do stupid runs, no runs at all or ignore the ball. I dont want to see that in 12.
I was playing with Milan in carrer mode and Zlatan got the ball and was 1 on 1 with a deffender. The deffender was on his left side and he was at the end of the penalty area on the right side. You could see Ronaldhino on left side at the end of the penaltyarea. Instead of going down against the goal so Zlatan could pass him for an easy goal Ronaldhino when even furhter outside the penaltyarea and decided to mark a deffender................................. :@
And atleast once in every game some aicontrolled players dont care about the ball. The ball could be 2 meters infront of him and you can see that your op that is aicontrolled which is 4 meter from the ball is going for the ball but your own player in your team wich you dont have any controll of since your controlling another player is just standing there and dont even bother to try to get the ball. This happens ALOT offline.
And lets not talk about when the deffenders try to catch the ball when your op has made a lobbed through to his forward. The deffenders sometimes fail and the forward ends up with an 1 on 1 situation with the GK.
The arm
Another major gameplay problem is that deffenders can hold on into other players with just 1 single arm and from that run at the same speed as yours own player.
Example: Walcott is running on the right side for a cross. The deffender (Maicon) aint fast enough but he holds walcott on his shoulder with his arm wich stops walcott from running away and maicon gain enough speed to follow walcott. Tho inreal life maicon would have no chance at all. Just watch Bale destroy Maicon. You didnt see Maicon stop bale with a magic hand. (You know what game i am talking about)
The pressure should be turned down a little too.
There is also other problem caused by bad AI such as players often run into each other.
Fix this for 12 and the game will be much more fun to play.
