If this was added, that would cause a huge break out in farming. If you were at the bottom of your minimum league offering zero trophies to an opponent, trophy hunters wouldn't attack you. This would cause you want to drop so you will almost never get attacked and therefore save most of your loot. With the TH11 update, Supercell wants to get people to buy more gems, but if more people farmed and lost very little loot, that would further decrease the need to buy gems. And if Supercell gets any less money from CoC, that may be bad for us players...
