Screw all these progression types, dude. I think devs should go further and make next logical thing happen - equalize stats of all enemies, armor, weapons, food. In-game progression must not be forced. It should be up to us to decide how we want to look like while exploring different biomes. We should decide what food does our character eat. Biome difficulty scaling takes away our ability to chose how we play the game, rendering most of the content effectively useless.
I paid money for this game and if I want to roleplay mushroom-fed druidess in leather armour strolling around freely in Mistlands, I expect that I would be able to do so.
