I had a lot of trouble getting the sliders to give me a realistic game on the Xbox One. I found the goalies were just not programmed very well, so I ended up having to put the reaction times on the highest slider and shot accuracy on the lowest slider. It still didn't give me enough realism though, as the game seemed wont to still score too many goals.
But I was letting the AI play itself, so that may have been my problem.
Hope the sliders work well for you (and if they do, I might steal them for my own use on the One
).
Looking forward to this.
