just what I think it would take for such an idea to work instead of dismissing it outright
just giv eme the point why you need it, and can not make this with buying and selling and that must not be different players. So why is that necessary, and will improve the game.
We could also set it so that the team taking on the loan player pays the full salar.
You better be successful in overpowering the opposition, because your economy is going to take a hit. The bigger the player, the bigger economic hit you will take.
it isn't just the salary, it is also the ability to get extra quality for free through connections. Which also generates extra money.
And is it no disadvantage to be stronger then you are for a season, even if you fall back after it ;) It is a clear advance if you don't have to do anything for it.
3. There is also no reason to loan players for medium teams.
