The problem is certainly not that biomes can host trolls and the like! Trolls are quite rare and easily avoided, and they spice up the black forest. It's a good thing if biomes are still a bit challenging after a while, and have some very tough encounters early in case of bad luck or ill preparation. I'd keep trolls as they are: a utter fear on first encounter and death, then somebody unstoppable in melee (with trunk) without proper melee equipment or a very good fighting technic. I hope that starred ones don't become ridiculous once you get high level equipment.

Imo, if there's a concern, it's about gearing to master a biome. I understand what devs are trying to implement, and it works indeed, from what I can see, but if high level gear is mandatory to access some areas or experience some game's aspects (like melee fighting), players shouldn't hide behind gear, and gear shouldn't turn early biomes into a mere joke. I mean perhaps not as radically as currently?

Perhaps next biomes encounters could not only rely on better stats, but also on better synergies. Take Greydwarves as an example. Currently, in non maxed troll set and in single combat, I fear only two-star brutes because I can't yet parry them with confidence, and blocking them with wooden buckler let to much damage through. What if, in late game, shamen would bewitch their brethren so that they move faster, they hit faster, they regenerate more, etc, and this would globally increase the required gear and player's skill to beat them? Wouldn't this be one way to have the denizens of black forest still a small challenge late game, but only in some wretched situations (a shaman's or a starred shaman's party)?

I wonder if some here aren't simply reluctant to live again what they lived when first entering the mountains or the plains, when next biomes are released!
