Why does the effectiveness of night bombing decrease in late 44? Is this just because of the swarms of German NFs. My understanding is that many human German players disband their NF squadrons because they need the pilots for their day fighter squadrons.
It is due to night fighters. Off topic but I am curious about strategy of disbanding night fighters. The one place the Luftwaffe can dominate late war is at night getting substantial kill rates of 10:1 or more. The lifespan in daylight against hordes or Allied escorts is pretty short. I find Germans late war reduced to holing up in a few places with no drop tanks to try and catch deep raids that my be flying past escort range. Even if good German pilots in daylight getting a 2:1 kill ratio the attrition from that can't begin to keep up with the 35 pilot a week replacement rate. Flying missions with hordes of untrained pilots is just building planes in order to crash them.
It what may be heresy to some I send many of the daylight reinforcement fighter groups to EF to boost CV there.
I don't have an argument against more Canadian pilots if facts bear out replacement rate too low. Something I do that may help Canadians that dates back to pre patch but I still practice is moving the FB's from Italy to southern England a couple of months before D-Day. Here they get Typhoons and rest up for D-Day. I also move all Canadian troops to England so they will be wanting their own air support. Finally, I only play as Allies now with the additional air HQ's. I put all Canadian bombers in their own command so it is easy to have them set out a few turns. I never fly Wellingtons on strategic bombing missions also and the Canadians have a lot of those units so I upgrade or put them in a port buster command.
As for pilot experience, you can go into the editor and see the base levels by calendar quarter for each of the combatants.
I usually play against AI but note even AI doesn't contest daylight raids late in the war. Allied AI does run air units too hard though with no rest and I should go look at their replacement pools sometime.
Good luck over Germany.
