I am suggesting that we can have a reward like half of the number of food rebate if we win our match via match making.
People are having problem with the food mechanism, and for high lvl king, we need more food to battle. If we have food rebate system, i am sure people will be more willing to use it to fight.
Example : a lvl 85 king need 200 food to battle. If he wins the battle via match making, he gets back 100 food. So if he has full silo (800 food). Usual way is he can only raid 4 times. But with food rebate system, he can raid 7 times , which is 3 times more.
Window user will also be benefiting from it as well, since no external source like advertisement is involved.
