Ok there are a few aspects of this which I will need to tease out, as I agree with you in some parts and disagree in others.
This is the part which I agree with you on. I think that factions should not be attacking their own T4s or bearers. For example, I have seen voltaries of skelos attacking kisthis fleshterer and tma the slithering before. I could rationalise this as them being a sinister and ruthless faction, but I wont. Aside from that, I like the changes. For the first time the environment feels more alive, and like we we are not the only adversary in the world. Ok time for examples.
Nature wise â Crocodiles are now hunting gazelles (as opposed to living in perfect harmony with them) and battling spiders. Imps which are maddened savage little beings attack everything they happen across, including baby shalebacks now. Cruel yes, but then so is nature. As far as the in-fighting between certain animals (eg-snakes, rocknoses) goes, I do not mind. It is common in nature for (example) different species of snake, spider, bird, etc etc to kill and consume other variations of the same species. Heck here in Australia, spiders even eat snakes!
Volcano wise â I enjoy watching the the voltaries of skelos do battle with rocknose kings, and also the other âpilgrimsâ dressed in reptilian armor. I do acknowledge as @jot29 pointed out that at times, yes they attack T4 craftsmen, however I just dive in and defend them, usually having little difficulty drawing their aggro.
Relic Hunter wise â It always bothered me that the townsfolk treated the bandits as one of their own and defend them. Every single time I battled the bandits, other citizens would start attacking me (aiding the bandits) instead of them! Even if they instigated the violence in the first place. Previously, if a gate guard had a confrontation with a scorpion, he would then come and attack me, as if I were at fault. Now they just return to their duties afterwards. And regarding Szeth, he is just the town drunk and not part of the expedition. Im not surprised they try to kill him.
Anyway this is just my own personal point of view on the issue. Everything just seemed a little to peaceful beforehand, in a land which is supposed to be frought with constant danger and hardship. I did enjoy your analogy however.
PS-thanks @roro4066 oro and @ninefow, you guys pretty much capture my thoughts on the matter.
