There was no way you could sneak up on anyone.
That, in a nutshell, is why 99.99999999999% of people that request night time want it. So they can "sneak up" on somebody without being seen and get free kills. Might as well wish for AFK drones all over the map. Might as well wish for your plane to be invisible to everyone, even though they're not to you.
Fact of the matter is in WW2 combat was a fair weather affair. They flew when it was sunny and clear, and didn't when it was otherwise. When you look at night time stories it's an entirely different kind of combat than what we see in-game or what 99% of all fighter pilots saw in WW2. Our equivelant of nighttime raids is akin to NOE milkrunning hordes of 50+ popping dar at the last second. You want night fighting? Hunt NOE hordes. It's not that far off, IMO.
There wasn't large scale dogfights and what most folks want "night time" for is just to sneak up and pick targets that don't fight back. If you ask me, that's what offline drones are for. No need to bring that into the arena.
