Isn't so easy to apply a -5 (entire 20%) to the players base.... that's why Im more follower of do a straight training closing for non promoted teams, don't allowing to train when players reach the 7* or the 8*... or maybe a specific percent between this...
I really don't belive that this will be done tbh, as some other tactical simulators Ive seen, the count only goes up... and this means that then the promotion would be easy once relegated, and that as the league does the groups using the AvQ...... the only way to do it is like this, with no discount...
This of course will need to think in some changes regarding the FAs... maybe think in some realism, like send us a message saying that, X, Y and Z star players of our team are going to leave....
and at this point to make it work, they can "leave" to a reserve bot team that can be added in hidden way or visual one, in our same team list with spots for players that couldn't be selected if we don't promote.... locking them ¿?.....
This needs developement an a good structure to don't unbalance even more the distances of stars that we actually have with the Fas tankers... cuz we wont ppl tanking with 8* 5-6 seasons to have 13* players, u know what I mean.... but something like I mentioned could be done if +7* are locked till promotion.
