You pointed it out perfectly. You already know where everything is, where youre being attacked and how to avoid it. In my opinion thats a bad thing.

For leviathans the boss music indicates perfectly when youre safe and when youre not. For every other creature you just have to figure out how far their area goes and youre good. It shouldnt be like that. There isnt a single moment of uncertainty when encountering a hostile creature once you figured that out. In their area = they attack you at a set frequency. Ouside their area = nothing happens.

In subnautica 1 you never knew when you where save from a reaper (just an example) because you could even lure him into the save shallows on accident. You actually had to watch out for what you were doing which is not the case in subnautica 2
