My worry is EA's track record of good ideas with poor execution. The idea that hitting a guy could sometimes lead to fights turned into any hit leading to a fight that you couldn't escape.
The physics based hit engine went from some big hits to every single hit was bone crushing.
Dumped pucks that were apparently too easy to pick up started bouncing to the top of the glass.
Players getting injured blocking shots turned into losing a guy per game for both teams.
And I think the final one I can remember, missing a check and hitting the boards could hurt you...turned into any missed check be nearly fatal.
EA has never had a problem coming up with good ideas...they've just always seemed to struggle with them not becoming a cartoon representation of themselves. It's like Wiley Coyote did the programming and thought everything looked too plain.
