No, it was the same way in 12. I know it's hard to get used to if you don't play a lot of goalie (which I don't either), but honestly, it's really the most fair way to do it. Otherwise, one person's CPU goalie who has been a brick wall all game, stopping 40 out of 43 shots could continue to outperform the other person's goalie who has only stopped 10 out of 13 shots.
At least in these cases, it specifically comes down to your skill vs your opponent's skill. I had a penalty shot in my game against Flyersfan, and he stuffed me. I tried to get a quick feel to see how jumpy he would be, but he did a great job being patient and following the puck. I was impressed. The biggest thing that will help you is just playing a lot of online shootouts. They're very quick and easy to get into.
This. I play a lot of online games (well, in the past, not so much this year except this league.) I also poke check a lot and always end up giving up fast breaks where I have to dive back, so I tend to put myself in the position to be a goalie in shoot outs a lot. I've probably done that 10 times against peope in this league alone. Patience is key as in real life. Follow the puck, hope EA puck physics don't you over.
