you can buy all the best players cause you can pay easily the salaries. These factors could create more gap between the first divisions and the others, anyway is really interesting to check what will be
I don't think it would create a bigger gap. I suspect, and hope, the opposite. If a team with great reserves and good income buy all the best players this would use some or all of the reserves while buying them and lessen the overall income, thus making the gap smaller over time. At first that team will gain an advantage ofcourse, but they should since they just used their reserves and lessened their income.
What is good about that is that it forces the other teams in the same league to invest their savings to stay competitive, and the result is more money out of the game in form of salaries. And also put bigger pressure on the higher divisions, keeping them under pressure to use their money instead of making major parachutes for when the times get tough. Training will also become increasingly hard if you want to stay in the top divisions, forcing teams to buy players that are allready trained to a high level from smaller division teams, also bringing more money from the top div teams.
Some of the transfer amounts goes to FA (out of the game), while some goes to other managers whom then saves or reinvests in new arena (cap on maximum attendants already introduced) or players (some % to FA and out of the game). Also there are the fee you pay when selling.
What I am trying to say is that this raise in the market prices was foreseen as a result of this seasons changes, with arena deconstructions bringing a lot more money into the game in a short period of time. The magnitude was perhaps more uncertain, and that is one of the reasons FA came back until further notice. Stabilising the market must take time, if to many factors to bring money out of the game to fast were introduced, this will also skew the balance and upset a lot of players (too many FA's would hurt those that have the best possibilities to -and are most dependent on training to sell (smaller division teams)).
There are so many factors to the balance of the game, and we have to remember that the main goal is to get a self-adjusting balance. Putting pressure on the top teams may be the key. I think we are moving in the right direction. But I think we all need a little patience.
