I agree, the ai on both sides had noticeable improvements from NHL 24. Many subtle gameplay changes that are rarely mentioned if at all this year.
Better cpu d ai defensive pressure when entering the zone ( 50 aggression is overboard, I use 10/100 and still very good and balanced).
Cpu ai forecheck pressure, and using the right dump ins. It's not solely the flip dump, but also the quick dump around the boards. The flip dump is also stronger.
cpu ai offense is very creative and unpredictable especially if you edit their cycle/shoot to lean all the way to cycle. You give an opening they will aggressively attack the net, you bear down defensively they cycle. Dmen shoot the puck and score, a big improvement made in NHL 24 and still consistent now.
The big issue is the goaltending and I've created a thread on that (cheap goals due to unnecessary goalie movement). If they fix goaltending, it's a very good hockey game. And clearly better than NHL 20,23 and 24 which were my favorites.
