More customization would be a great thing to have, or just unlocking some(not all - not sure if there is anything really other than hair that is specific) the race specific items would be great too. Some things should remain race specific(if there really are any other than hair).

While I do say that, I also would prefer they focus on making more content that extends the story, gives us more side stories(more along the Coil stories, which I haven't even done most of them), and basically anything along those lines. Just more depth, and use of areas that haven't seen anything in YEARS, if ever.
