I play as a 2 way defenseman, so I only need 55% right now to get a good rating, and I agree completely. The game is so quick to dock you points even if it wasn't even your fault, but then like you said pokes, blocks, etc barely give you points even if you were to defend against an obvious scoring chance. My biggest issue so far is the absolutely horrible teammate AI. I can't even count how many times my teammates make a mistake and I have to pay for it. Other team streaming up the board and I'm right on their tail? Teammate decides he needs to come over and help out, leaving the center heading for goal to one time it in. So many missed assignments by my teammates only for me to take the hit for it.
I'm honestly close to just trading the game in. It's really no fun at all to go 2 periods with absolute shut down defense, only for a teammate to leave someone open shift after shift so the other team can get several goals in a row to come back.
