Suggestions on some defensive methods

My assessment is pure rubbish. The so-called castle and town center. In the third era, once the weapons with heavy armor are attacked, the so-called sentry and the defense crossbow in the town center are a lump of :heart::heart::heart::heart:. I strongly suggest that the crossbow in the town center, the sentry and the large fort can also be damaged the same as the weapons without armor. This can make the siege weapon useful, and also play the fourth era, Let everyone experience the characteristics of their own country, and also prevent the cavalry in armor of the third era from killing farmers without brains. The so-called defense of castles and towns, like furnishings, is meaningless. This is a virtuous circle and balance!
