What slider do you mean? Is there anything that affects general ball control too? I am noticing a lot more now the differences between players in terms of ball control though
My passing error is currently set to 65, when I combine that with playing on semi assisted it's really hard. But I do notice the AI giving the ball away more, with weaker teams, than I've ever seen before in a FIFA game on 65. I can only imagine what it's like set to 75-80. Surely players will be barely able to hit any passes at all?!
Also don't know what to do with the player run frequency. I'll probably stick it on about 75-80. Set to 100, it tends to make games play a bit too end to end, but I do like the increased AI aggressiveness in terms of player support. It's just that I don't want to set it too high and leave me able to counter attack teams too much.
I'm still over the moon with the acceleration and sprint speed sliders, they've revolutionised the game for me. Before, I would always try and slow the game down to a realistic looking speed, but now both sets of teams move far slower in terms of turning on the ball etc, and I don't have to purposefully slow things down now. The pace of the players feels perfect, it's as if it gives everyone a bit more weight to them and emphasises their touch on the ball rather than acceleration speed. Lovely.
