As a very casual player, I've maybe played 3 full seasons total spread across 10+ years, I enjoyed the extra tinkering and nuance associated with the added AAA players. Also, when I signed up for a team recently, I didn't realize that AAA players weren't included until after I completed my team. Maybe this was an oversight on my part, but it might be a good idea make it more abundantly clear to the user before they start building a team.
