You're insane. What use is tanking with national teams??? And team quality in national teams is decided by the best 14 players, so adding 80% players does nothing but make the teams worse. It changes nothing about how quality is calculated. And national teams playing for associations might be the silliest idea I've ever heard. Why would you even want that?
Let new managers bring their teams up to the level of other managers, don't bring established managers down.
