the Drow/Goblin walking around is probably a lot more tolerable when they're in a group with others
Possibly ...
Still, we are talking here about one settlement that was just raided by Goblins ...
And another settlement that is ambushed by goblins at regular basis ...
and yet they dont know where it is, isnt that weird? 
Its like: Mistress, scouts from south regions didnt returned ... just like the squad before them, and squad before them and squad before them! > Hmm, its probably nothing, keep searching everywhere, send another small, easily defeatable squat to the south. So ... still nope from me. :-/
Half done, half broken mechanic that creates more problems than it adds ... isnt something that should come to this game officialy, if you get what i mean.
There is some effort between modders tho:
