At first the CPU felt to fast for me as well, but eventually you get used to it. One thing that helped me was trying to funnel the players against the boards and force the players away from dekeing and breaking you down in the middle. If they do, take one of your defenders in the slot and try to hip check the defender towards a spot you think the deke is going to finish and catch the puke. Its more effective then a regular hit.
There is just few things sliders can do to fix the bonuses the CPU gets for Superstar settings...just like All Madden on Madden 2011. I wish this wasn't so....but Ill see if I can play around with them some more and balance it. I am toying with the idea of changing the penalty scaling, but I think this might upset the shot total since both sides get more shots with a 1:1 second scale on the power plays.
