This adds up to 694 leagues for a total of 1771 teams, that is, an average of 2.46 teams in each league of 16.
The rest of the countries have 4 divisions, 85 leagues for 121 to 382 teams (1.4 to 4.5 teams per league)
or 5 divisions. with 341 leagues for 596 to 1647 teams (1.7 to 4.8 teams per league)
After the change they would remain;
Asia___ = _209 teams => 5 divisions => 31 leagues => place for 496 teams.
Africa__ = __46 teams => It would enter together with Asia and Oceania
America = _426 teams => 6 divisions => 63 leagues => place for 1008 teams.
Europa_ = 1030 teams => 7 divisions => 127 leagues => place for 2032 teams.
In total 3 Confederations with 221 leagues, for 3,536 teams where the current 1,711 would give an average occupancy of 7.74 teams per league of 16, still leaving room to grow and double the number of users.
Reducing the number of leagues to simulate and manage from 694 to just 221 would surely save a few dollars on server costs.
And I don't count the number of leagues that would become the leagues of "Big" countries with their own national leagues.
