It won't change. It's been like this for years now.
I found that the only way I could get any fun out of this game was by playing position lock.
When my CPU teammates have the puck, my opponent would let them walk right in.
If I was passed the puck, it was like skating through a gauntlet of angry muggers and lumberjacks.
The game is programmed that way for a reason. The AI is so brutal, that if your CPU teammates attacked the puck like they do, your CPU opponent would never score a goal.
So they make your teammates docile and give the CPU boosts so that every player they control is a combo of Lucic and Crosby.
I'm completely done with this series. They can add all the bells and whistles they like, but the gameplay and AI is absolute garbage.
