CPU teammate penalties should be turned off completely. I should only have to kill a penalty when I make a mistake.
Goaltending needs to be returned to its launch-day state. This was the first game in years with good goaltending, and the first big update ruined it. It is so much easier to get basic slot shots off in this game than in real life, so they should be made far less effective than slot shots in real life. Updating the game to have them go in more often has added to the randomness of the game. More randomness means it is less likely that the more deserving player will win the game. Randomness is the great equalizer. There is NO worse feeling than losing a game you deserve to win, because your opponent got lucky. NOTHING else comes close.
Also, it's silly that there is a timer on full pressure. If the puck doesn't leave the zone, the pressure shouldn't be reset. It makes no sense. Buuut the amount of time the puck needs to be out of the D zone to relieve the pressure should be lessened.
