Other biomes

Me and buddy decided “we stronk now, we live in Wasteland.” and we spent one 7th night there to be met with nigh infinite infernal and charged zombies. We relocated back to the forest biome and found only Radiated zombies. What is the point of *living* in the Wasteland or other biomes when you can simply just live in the forest and then make “quest runs” in the wasteland during the off 7th days.

Is it purely for the challenge? Forest=ez mode while the rest get more and more difficult with Wasteland being on top?
