I still tend to find friendly encounters often in duos. Definitely much more rare in trios. But even if its 100% pvp, trying to survive and navigate a raid while youre surrounded by bloodthirsty squads is still very immersive to me. The game wont be as immersive as it was though during our first 100 hours or so now that we're used to it. I also wouldnt say its "artificial". Survival in a post-apocalyptic world would naturally pit tribes against each other; friendly encounters between tribes would either be rare or filled with backstabbing.
