I understand that making each level of building has an increase in cost. But it seems it becomes a bit rediculious when you get up over 15th level for the Headquarters. Five levels of very high resources which yes can be gotten but only after a long time and then subject to being taken if you are attacked. Then doing it again and again after taking villages that have not gotten that far. They you have to spend a lot more resources on coins and to make a noble. To help the game along perhaps the amount of resources should be lowered so the players can have what they need to really compete in the game.
