Why does there have to be a niche for a new plane? Seems silly to me to say "....we don't need the A-36 because the P-51D is better." Who cares? If it's only about having the best of each model, then maybe we should get rid of some planes. After all, we don't need the La-5 because the La-7 is faster an better armed. We don't need the the F4U1/1A because the C and D models are faster and carry more ordinance, and so on.
Not everybody feels they have to fly the latest and greatest planes. Personally, I grow weary of seeing the same planes everywhere; P-51D's, Spit XVI's, La-7's etc. First time I went into the WW1 arena, it occurred to me that it should be renamed the DR1 arena because that's what EVERYONe was flying!!
I think it's about the experience and not just flying a plane with which one can achieve the most kills.
