Exactly what the title says. All I see is wood bases because there is no real reason to upgrade your base. For example in A2: Epoch cement was the norm because people didn't want their base to get chainsawed through. Not saying I'm different from everybody else because my base is all wood and I just either ignore metal sheets and metal poles and base supplies like that cause there is no reason to upgrade so I don't really know what this stuff does. So basically what I'm requesting is a way to break down walls or to nerf wood to force people to upgrade.
