Hmm, in a perfect world I'd love to see some amazing environmental effects: the pinnacle of which would be a tornado or tsunami, as it would be a game changer:
Pilots have to plot orbits around the storm, otherwise they'll get pulled in. Trying to catch up/run away in this fashion would be very interesting- turning around would expose a huge face for the wind, and would pull you in faster. Also, slingshot effects would be nice.
Gunners, trying to aim in that would be a whole new skill.
Engineers: Engines would become more important than hull- If the engines are out you'll be pulled in very quickly. A
Oh, and gamemode? King of the Hill, in the Eye of the storm- you'd have to fly above the storm and attempt to descend inside the eye. As this gap would not be large it would only allow for a single ship, hence it would be very easy with a harpoon or ram (if you plan on suicide) to displace them.
Alas, I know this won't be implemented ever, but I like the idea of battling the elements and high risk.
Cheers for reading.
EDIT: There would be no dust damage whatsoever. That would make life too impossible, surely.
