Good List Evenhaim!
IMXLR8N, Bearcat never saw combat in WWII, that puts it outside the realm of potential planes right there. Plus if you did add it, it would have to be highly perked or it would unbalance things. So why bother?
Night fighters were a very minor minority compared to the vast number of planes that actually flew and saw combat. Plus you can't have a night fighter without having at least 8 hours of darkness in which to go hunt. Currently people get hugely upset about 20 minutes of dusk. Who's going to pay to play in 8 hours of darkness? See what that does to your nightfighters? Again, shoulder shrug, why bother?
DO335 Arrow, hmmm ok, late war plane, very few in production.
I guess after ever other plane that has been asked for BEFORE the arrow is in the game I'd be ok with adding it.
But I wouldn't hold your breath waiting.
There is a very big list of badly needed planes. You didn't include any of them at all, just late war monsters. Sorry but AH has enough of those at the moment.
