That would be horrible, safe zones arnt realistic in this environment, if there was a safe zone, there would be no outbreak, they could eventually set up more and more and wipe out the infection. Maybe some kind of random woman begging you to find and save her lost child in exchange for food or whatnot would be a good idea to try, but the lack of trade (Especially NPCs), just bartering and scavenging is what make this game realistic, this isnt a MMO and it should never be made into one, it has a unique concept, the idea of instances could be good, but turning it into quests or XP or whatever would make this nothing more then a WoW wana be.
