But that would add to immersion. It is realistic that it would be relatively easy for high-powered bandits to rape and pillage relatively unprotected small villages, although it of course also means that the rewards in items and gold would make it not worth it.
I`m trying to say that existance of completely newbie location is not very realistic.
You're wrong. It's completely realistic that not every single village in the game would be guarded. It's completely realistic that stronger monsters would be likely to hang out in some types of location whilst weaker monsters would be likely to hang out in others.
Oh, come on. Why should all monsters of similar level be in one place? Is it some solidarity?
Yes, some intelligent ones looking for more cool shiny things that they can rob in wealthy cities, other looking for power there and there is best trained guards.
But what about less inteligent or ambitious foes? I think they should search for such places because they`ll be mightiest and nobody`ll fight them there.
And there are reasons why strong intelligent villains can search for remote poorly guarded place.
It`s good that world is changing and strong will take a place of feeble. It`s more realistic and interesting then if you clear all newbie locations and there won`t be anyone anytime soon.
And I didn`t ever say that it`s ok just to give some uber equipment for goblin villagers and make them all high level fighters and mages.
Added: If you ask what`s the reason of all the changes - well that`s up to scenarists.
As example, while in the city protagonist smashed down head of criminal organisation, reveal activities of blood cult and persuaded mayor to increase sanitary state of sewers. So parts of these organisations escaped city, and, just as these sewers monsters, swarmed the countryside. Or elven council changed their policies and forced all those fearful monsters out of their forest. There are thousands of posibilities.
