Personally, I hope the waters are a peaceful place to explore. I'm not so sure why everyone is always looking to be attacked all the time.
I just want interesting and different places to explore. I'm not looking to be fighting all the time. I won't mind the rare aggressive see creature, here and there, but I shouldn't be prevented from just swimming around and exploring. I do want to see ship wrecks and such return.
Yeah I want waters to be peaceful too. Lots of passive, friendly fishes. A few "lesser" agressive ones too (like slaughterfish).
Sea monsters should only be in deep water. And they should be big,
rare, deadly, incredibly strong and terrifying.
