I would tend to agree. But I guess that would be at the level of not getting much and playing football because you love it. EG Conference north and south. Rather than for £250,000 a week and the love of money eg Premier league
Absolutely every game out there will have exploits. Its impossible to avoid. Its up to you to make the choice of playing as it is meant to be played, or ruin your own game experience by cheating. This exploit that you have found willl not be of any bother to me or to most of the other members of this forum.
You make totally unrealistic offers to a player, with the £1 contract and high agent fees. Yet you complain about the game reacting unrealistically? It is a game after all, and if you try hard enough to "break it" you will eventually succeed. Its not human beings with human intelligence you are negotiating with. Its a bunch of code which always will have its flaws. Give realistic offers, and you will get realistic responses.
I think a lot of people really seem to be missing the point here. If this really works, then it doesn't matter what you offer the player as wages. It should matter. If this works, then there are no greedy players in the game, there are no players willing to work for lower wages at a club they love. It means that there's absolutely no negotiation with the players whatsoever.
