To those who think an external view will confer combat advantage, it's not an unreasonable fear, and I'm not going to immdeiately dismiss it out of hand, even though I don't share your fear.
I fly a lot of combat flight sims, things like DCS & BMS, where an external view can be an advantage in that it can give you a quick glimpse of where your opponnent is in relation to you.
It's of very very limited benifit though, as you then still need to get your nose on the bad guy, still need to lock them up with the radar, still need to target them with weapons, and still need to be able to fire accurately - especially with the gun - to turn that quick glimpse at the external camera into any kind of advantage at all.
Trust me, it's not the instant "I WIN!!!" feature you think it is, especially not when the other guy can do exactly the same thing, and is enjoying exactly the same "advantage".
In Elite, you don't need to do this, for one very simple reason.
You have a scanner with 360' coverage that shows you exactly where your opponent is at all times.
And if you *really* want to make sure nobody can "cheat", just make it non-functional in combat. You'll lose out on the possibility to take some really cool screenshots on the rare occasion it occurs to you to do that instead of shoot the bad guy, but whatever, nobody has an "unfair advantage" this way.
Or incorporate that "second or two delay where you can't control the ship while the view pans out as the 'drone' deploys" that was mentioned. Or disable control input while in external view, whatever. There are *many* ways to make sure nobody gets some percieved, but actually extremely brief and limited, advantage.
Sorted, and everyone is happy.
