I think everybody agrees that this Transfer system is really sucks. There is a lot of money goes out of window without any use. While there is no economy system in the game, this wage bidding is really insufficient. With economy system i mean, flactuating economy. Also player estimated values are nearly useless in this system.
I agree that there must be an open auction system(and example of the shomyguca is a good one), so the transfer market can be more active. One addition to all this thing maybe off the record thing but in the earlier seasons (don't remember which one, 4th or 5th i think) It is mentioned that there will be an implementation about National Football Association - not National Teams)
Maybe (if it will be implemented) those penalties on the transfer prices will be transferred to the FA (for example %1 of the penalty) and used for national teams.
if we come back to our main discussion, estimated values are calculated by player abilities only. With a flactuating economy system and auction-based transfer market these values will be calculated more efficiently.
I hope, I told what i want to; and i hope it was understandable
kind regards
