I like your idea. I just wanted to add a little bit more complexity to the game, but I guess simplicity in this part of the game would be better. Cuz I would like to have my base look like a disco ball without having to worry about a part of it being more vulnerable than the other. But if that’s the case, then the metal shouldn’t be as powerful as I suggested because that would leave concrete with not much specialty when it is in the legendary tier. Unless we make concrete even more powerful with even more damage absorption making it extra difficult to raid
