you guys totally didn't use tgm/mod to build, lel. My settlements have 3-5 turrets max, no more is needed. I'm level 70 on survival and never was i like "hmm maybe i could use couple more turrets. It's just i understand how the system works, a lot of people just give bethesda too much credit. They think settlers have some complicated AI, care about how comfy beds are, how loud generators are and how well you decorate - they don't care. And if you ignore settlement attack, the attackers don't destroy your defenses - there are no attackers, the attackers spawn when you arrive, they don't exist otherwise. The game destroys your defenses and resources automatically, that's how it works. I don't think there's even an attack that requires 100 defense... Your numbers are skewed by umm.. cheating, to put it bluntly.
