Teams that don't achieve promotion should lose quality

It's a popular and legit strategy, but just like in the real world, why would top players want to stay in a team that doesn't get promoted, sometimes for several seasons? Teams that don't get promoted should lose quality, this would avoid having competions with teams with >130% that didn't do anything besides tanking for months. The game shouldn't reward these lazy teams going the easy path.

Edit: or at least have a team quality cap. People would still tank to improve 2/3 players while the rest of the team would be 1star players, but at least it wouldn't be a whole team of 10 star players and maybe they would even stop doing it because it wouldn't be worth it. Kinda surprised t11 allows this, since it's a easy way to get top teams without buying tokens.

1 top team without buying tokens may well encourage 13 others to buy if placed in the correct league. Nordeus thinking?

Could also encourage 13 others to do the same, reducing the user activity in the game because they don't need to watch games,ads,etc. Could also encourage 13 others to quit because the game is rewarding teams that just sit around for months doing nothing, making the game boring and easy to win with >130% teams.

As it is at the moment, I believe that is hurts more the game than is helps active players and devs. Why would you waste money if you could get the same result for free? You'll probably see 13 teams tanking because of 1 top team that reached that level because of tokens that the other way around.

Let them lose 10% as penalty for not promoting,

Teams with 9* = Promoted. Thats one suggestion, the second is, if you promote with a 120% team, you face +2 Levels in CL/Cup.
