The wall is one of the controversial structures. However, some defensive civilizations need walls. That’s why I want to make a simple suggestion to prevent them from building too many walls over two or three layers.
That’s what gives the wall destruction XP. When this happens, they don’t need to adjust the wall’s HP or its price, it creates another reason for the player to break the wall. The important thing is that they shouldn’t be given construction XP.
If the wall is destroyed, it can benefit the opponent, the player trying to build the wall will only build the wall as needed in the correct location. In addition, conserving resources by intentionally destroying pillars can also be blocked.
I’d love to hear from you on this proposal.
