Haha, good imagination tomomi. That kind of gameplaying mind is good for open worlds. I use to set recruiting towers in every settlement, give food, water, lots of defenses, walls, turrets, etc, and....when a settlement is under attack and I don't go there, if the settlement has, for example, 20 settlers, after the attack remain 3....WTF, they have turrets around the campment, lot of them. It's like the game don't work fine with this system and no matter what you build...and i don't like that. Must say I play without use the fast travel so...attacks sometimes are constanly, even 3 at the same time...thats frustrating for me...because the settlements seems to be unable to defend themselves.
