These games have always been tuned around forwards, because they almost have to be. Scoring is fun, and for a young or casual fan that's probably what they notice most about the game, because it's what gets the most attention. Can't really fault them for that. If you pick up the game as a casual fan and can't score, you probably won't play it very long.
The game isn't tuned so that young and casual fans have fun scoring. Tuning is based on creating a competitive, even playing field between offense and defense. Obviously, defense is a very challenging position to play and I agree it needs a boost. Except for Truculence which I agree needs a nerf. I also think that possession of the puck is regained too easily by the carrier when it's poked away. That doesn't mean that we specifically tune the game for offense though.
I also agree speed is too high. I'd love to see this get a nerf as well. All this feedback has been relayed to the team. It's possible there could be tuner updates in the future.
