I also like the early war rides, and they far out number the premimum rides that are left for the mail arena. There are several different people out there who like different planes and or different vehicles.
My favorite ride is the Hurricane Mk1, I know I am gonna get wacked a lot by LA-7's, Spit IX's and Niki's and I don't care. I enjoy flying the older planes and it is very satisfying when you can take out one of the "premimum" rides with an early war bird.
You also might want to consider that there is a better plane set in AH than in just about any other flight sim out there, or at least the Massive Player ones anyway.
I do agree however that planes lie the Ki-84 need to be in AH, and have no doubt that they eventually will be, but development takes time. I have wanted to fly a Stuka every since I started playing AH a couple years ago, and I am very excited about the new update because I finally get to have it. Guess what, I will most likely get shot down a lot in the Stuka, but that is okay too, it is all about the fun and sheer joy of flying to me. I would also like to see the Brewster Buffalo, IL-4, Commonwealth Boomerang, Z.1007, Ki-43, Fairey Firefly, I-16, D520, PBY Catalina, B24, B25, He111, Do217, P-61 and several other planes as well. All we can do is take it as we can get it and remember that development takes time.
