Allaince Mine Battles and donation
Keep the donation area for crop there but make it where you have to build and donate troops to your allaince. Make the Mine battles where you command the troops you donate. Makes it more team building. Right now 6 people controll while ours are slaves gets boring after a while. Let Allaince members use others members cities to move around or share troops from one city to the other but keep the starving system working. This would make it more of a true alliance. As an alliance you should be able to help each other in battle
