I'm not trying to sound like a you-know-what here or anything, but is the RPG / progression element really more important to you than good gameplay?
You aren't alone in thinking this, but I just don't see it. I would take solid, balanced gameplay that depends on the skill of the players and how much they know about hockey over the progression carrot every single time. I like the satisfaction of knowing that I won or lost on the merits, not because the other side had cards or boost packs or abilities that did not match my own.
