Frostbite is an EA engine designed to encapsulate all of their games under one hood.
Unforunately, documentation is horrible and studios have to put countless hours in to transitioning the engines to Frostbite with typically no benefit.
In the social media world (especially the echochambers where the 'EA sux' circle jerks run strong and deep) the kids say things like 'Frostbite would be awesome' with literally zero idea of what they're saying. They only say it because all of the other people who hate on EA for fun have been saying it.
This article lost me at this line:
"When playing NHL 19, there is zero creativity available at your disposal. "
That is statement made by someone who gets stuck in the patterns that NHL gives you and other players so there's less responsibility to be creative.
However, there's PLENTY of tools at your disposal to be as creative as you want. Just because you are unaware or unwilling or incapable of executing said creativity with any shred of success does not mean it is absent.
"I buy the game every year, play it a few times, whine about all the issues, let it sit on my shelf untouched for the next 10 months, "
How does this qualify as someone who has any authority to say what NHL 20 needs? If you only 'play the game a few times' - you're in no position to assert what NHL 20 'needs'.
