What is happening now by stopping troops transfer, you create a problem much greater than when you stop city transfer. The strong players are inviceble, and the players with a lot of money will jump there city's next to other players, and attack from clpse by. You don't even have the time to clear your city, before an attack. I think that is even be more unfair then transfer your troops to other players. This is what some players do, and other players who are being hit by these people are walking away from this game, because you can never beat a strong player.
