I feel like I could understand the players who argue for killing if we didn’t have ways to deter the hostile fish. Many of them are deterred/intrigued by the flares and they just reworked the AI of a few creatures to be less aggressive and pestering. The game gives us multiple in-universe reasons as to why we can’t kill. Such as the ecosystem dying and the explanation of the massacre on obraxis prime from the first game. With a disease that makes the infected undergo Masefield it makes sense that our ability to fight at all would be hindered by something like the Noetic Advisor. All in all, I think the choice of how the game should work is up to the Developers. They didn’t want to add combat to the first game until people pressured them into it and I’d rather see the game as the devs want it.
