It a mix of cheaters, network issues and how EA imagined the game. I think that they are changing the gameplay every now and then. I don't know if it makes sense 😕. Yesterday for example I saw a change in gameplay. Defences are more compact and defenders mark strikers closely. Everybody now is passing and turning. They also boost some of the tactics. Now I think is 4-2-4 and playing with auto-defend also was boosted. I don't understand how to play this game anymore. I had the same problems. My players wouldn't stay in formation. They would just run randomly so I lowered the graphics. If before I was playing with Max of 20ms ping and having these problems, now I play with 40 ms and my team is more organised. Hope it helps you.
