I didn’t vote in the latest poll as I personally don’t see the point in CPU teams buying players from human teams until money is returned to the game, rather than investment points. I don’t quite understand how to vote unless I know that money is, or isn’t being returned to the game as it used to be, rather than how it is currently implemented.

It is most likely that money will return to the game as it was before, we’ll have a poll about it when the time comes. But as far as buying and selling players go, money is already back to the game. The transfer budget is not a separate money bucket, it’s just the amount from your total money that is available for transfers, so whenever you buy/sell players you’re dealing with your money balance so no investment points involved (except to limit how much from your balance you can spend).
