The 7m IMO is no where near correct, for every one that joins another leaves, so while it may show almost 7m how many have left the game, remembering it takes 70 days to delete inactive teams.
As for the suggestion, dream on. Nordeus will have made millions out of this game, you think they would risk losing money to appease the minority.
Do the sums if only 20% spend 1$ a season, or month in real time, add in advertising rights and video commissions. The game is a gold mine.
