You are welcome to join the quest to find the theory of everything.
Too late. I already found it.
Anyway, having a system for making trades here is really difficult to fathom given the complexity involved, but I like that the idea keeps coming up since maybe one of these days we'll have a break through revelation with this. The way things are, though, is that it's difficult enough to find the cheaters operating through the transfer list. I have my own personal favorite ways of zeroing in on cheaters, but it takes creativity. Adding in a need to evaluate market value for players in trades would make the net I cast out so full of holes...
Maybe if the idea is we want to be able to move players around between teams, player loans might be a different avenue to look down since it doesn't involve transferring money, which is the main reason for illegal player transfers. Of course, that notion brings up a whole slew of other issues to work out and would really make this game complicated. If you want to explore that idea, I'd be interested in seeing a new thread kick off a discussion about that.
