I think the FA's are great way to fill teams rosters (salary cap) and are the best way to transfer money out of the game. How many teams are in the minus? Most of the teams playing BB are generating extra money to the game. Sale % reduction does not deal with the money generated.
Currently the prices are pretty stable. If you are making near 100k a week, you can add a player per season. Great all around players are still a lot more valuable.
I don't want to go back to the time where 8-12k salary players demanded 1,5-1,7mil transfer fees. Even as free agents...
I don't tanking in the highest league, but I'm not that sure that those tankers have an easy way back to the top div. Atleast not in the larger countrys. Obviously the salary floor needs to be risen a bit. But I don't see a problem with the training system. Rookies here are not NBA rookies. They can not contribute right away. People are still paying high sums of money for the top rookies. If you are planning to train that player for your own team. That's great, but if you are training him just for sale, you're going to lose money. If you want to make money, train your own draft picks and sell them after a season or 2.
