While this may be a "fair draft" when it comes to national teams, it would not be fair when looking at a club level if I understand this correctly. If every nation is getting the same amount of rookies with 10 or 11 potential then those nations with a small amount of users are almost guaranteed to draft a 10 or 11 player in every draft, giving them a massive advantage on their club team.
I think having more users should be an advantage for a national team (I know that is easy to say as a USA user), but if you have more users you should have more good players to pick from and this encourages individual nations to grow their BB community (though I recognize that is much easier for some countries than others). However, I don't see why we should try and give 50 users the equal shot at a gold as 1200 users.
