If it is team work you want to prevent, dont forget travian is a team game.
it is? Then how come I can't push someone with unlimited resources from my market place? Yet he can park his troops at my village and use all the resources i produce?
Sorry, but it is a system abuse. If it is not, then market place should not have a limit either on pushing players, since it is a team game. Specially now as the players who push should be part of the same wings.
