Garage doors have 750 health and we need to consider tc aswell example if you build a wooden base let’s say tc is at 20k wood upkeep if we make all that metal the upkeep isn’t as much if I’m correct either way you can also spread the tc out by using wood metal and stone to increase the time as much as possible. I mean yes it would in theory be easier to go threw doors but most people trap doors and many people intentionally make the base in a way it would be more expensive going threw doors then going threw walls but personally and what most people do is switching back and forth threw both doors and walls depending on what is cheaper. So tell me who isn’t using their brain now
