The process is set up to add new leagues/divisions based on how long and how many teams have been waiting. I thought it should have added a few of these as second divisions to existing leagues, but I'll have to look at the numbers to see exactly why they are new leagues.It might be that there were just enough people waiting to hit the "new league" numbers. The World building process is trying to balance breadth and depth as well as not make new users wait too long to join leagues.
I agree that the process should be looking towards 2nd divisions right now, so I'll see what was going on, but it probably fell to where the new users were waiting X number of days and did not get pulled into an existing league or new divisions, so the only thing left was a new league for the country.
The new leagues will not affect your FA market initially. As the new league gets closer to its 8th season, it will start producing better players, so you will be competing against more clubs for top players, but there will also be more top players. Also, these new clubs are only competing against each other and do not need top FA players. They are essentially season 1 teams and leagues. As they get more seasons, their money will increase and so will the wrold's competition for the top players.
The final vision of how the game works best is to have many countires with multiple divisions. We eventually want to have international competition and that works best with many countries in a world.
I am prepping some worlds in test to test consolidation, but there is still a lot of work to do to make sure consolidation runs smoothly and isn't too tough to pull off. As I work on that, I'll take a look at the code to produce new leagues vs new divisions and see if I can balance that a little better to go for new divisions.
