I'm mainly seeing this in Play Now Online. I can't speak for the other modes. Personally, I didn't care about the layup success rate, because my attitude was "All layups don't go in.". When I went in for a layup, it was on mainly on fastbreaks, plays where the my teammate was cutting backdoor to the basket, or I had speed advantage on the defender. Now, everyone just uses the hip-riding animation to make a beeline to the basket, and shoot like well above 55% on their attempts if you don't foul them. With online players, you can play good positional defense, but they'll keep turboing against your defender until they finally get the hip-riding animation.
