yes, and? WWII daylight fighters still didn't fight at night.
And that has always been the poorest of arguments not to have night in game. Or for that matter to not have night fighters like the P61 in game
We have all sorts of things that we both do and have here that WWII planes, and for that matter GVs didnt do.
Dive bombing heavy bombers. Maybe happened a small handfull of times in WWII. Here its common.
Heavy bombers also didnt fly around at low altitudes inviting everyone to come shoot therm down.
For that matter if you want to use the "Daytime fighters" argument.
Daytime fighters didnt have on board radar. Which all planes and GVs have here. That was pretty much reserved for....Night time fighters.
They also didnt have little numbers floating around them to tell the pilots if the planes were in gunnery range or not.
Most knocked out tanks werent taken out by a single planes guns. When that happened it was usually by a group of planes. Most tanks were taken out by bombs.
Tanks were able to hit things so consistently at ranges that make the target look like a small dot even at full zoom in ways that would make an M1 Abrams envious. A single base couldn't support an unlimited number of planes all at once and larger heavy bombers usually needed a large field.
Point is there are all sorts of things that are done or we have in game that are anything but conventional to how things were or were done in WWII.
so the argument of "WWII daylight fighters still didn't fight at night." is illegitimate at best.
And even with that your claim isn't accurate as there are several instances of daylight fighters being used at night. For example A number of Lightnings were modified as night fighters. There were several field or experimental modifications with different equipment fits that finally led to the "formal" P-38M night fighter, or Night Lightning. A total of 75 P-38Ls were modified to the Night Lightning configuration, painted flat-black with conical flash hiders on the guns.
That number of 75 alone for one single plane dwarfs the total number of flights heavy bombers were used as dive bombers in WWII
