I have only focused on building and expanding my settlement in Sanctuary. Me being a newcomer to the settlement building aspect of fallout I was afraid it would be attacked often and destroyed. So I created a lot of defense and a lot of water and a decent amount of food. I have around 30 food, 150+ water and 330+ defense. Is it overkill? I have never experienced an attack on a settlement I've actually build and I'm kinda getting annoyed by this. So is it possible to reach such a high level of defense, that no one will attack it?
