Just make it an SP only feature, and cannot be used in MP. That way those that want it can use it and those that don't want it due to concerns over possible exploits, don't have to worry about it.
Its obvious the 'combat advantage' reason is not the real reason external view is not allowed, as such a view could easily be inhibited when a ship enters combat. I think there is someone high up in the dev team who has put their foot down on this issue and will not budge.
I find it ironic that in the hanger they force you to look at your ship from an external view with no external cams mapped to internal cockpit screens - just the full 3rd person view which even rotates a little!
Immersion for one senior dev is not immersion for everyone - it is subjective. You will find that more people will feel connected to the ship if they can actually see it.
I find it rather selfish that an available feature is deliberately withheld from users because others know more about what we enjoy than we do
Can a supporter of the cockpit only view please explain to me why my viewing my ship externally will in any way affect their immersion. Why support an cockpit only view ? Why not support a wider choice - if not for yourself, but for others who would enjoy that.
Elite is about freedoms, not restrictions. Give us the choice.
