I like the structure here, in terms of the rewards getting better for making it further.
IMO however, I would like to see the rewards across the board improved. There should be a chance to get a legendary in season mode, considering it's really the main game mode (a very small chance, and don't even tell me that getting 2 draft picks is a chance!).
I for instance have played 10+ season and only once gotten an epic when I didn't win the season. That's at least 6 seasons worth of time for no useful rewards. Basically, an entire month of real time worth of rotating players every hour without a reward.
The more I think out loud about this game, the more I wonder why I ever played it at all. I doubt I'll start playing again without really major increases in the rewards.
