nt leo faria but you killed tier2 when you allowed for a single transfer window year long. And let me explain:
Tier2 teams have a few choices when it comes to revenue in a franchise league game. It's either the tier2 is stable enough in terms of viewership and sponsorships that by competing alone, they have income. This is currently not happening, and that's why plenty of orgs are dropping.
The other choice is selling their players to tier1 clubs. But that is also impossible, as the only transfer window is at the end of the season. By then, either your contracts have ran out, and the tier1 teams get the players for free. OR you're risking on paying wages for a roster that won't play for another 6 months. And many teams choose to drop their players and save those 5x6 wages instead of hoping some team will splash the bag for them. And then you don't even know if they'll come back to the game.
