I don't miss them, I hated them.
Sea dreughs were cool though.
Indeed, but we can't even attack in Skyrim's underwaters.
Imo, Skyrim's underwater is a fail on every level. Visuals, animations, gameplay, exploration and stuff to find - all fail in terms of underwater. Lol.
It's like... above the surface, you're playing Skyrim. Awesome.
But below the surface, you're playing something even worse than Oblivion. Horrible.
