Well, I guess the game has "Grown" in my absence???
Doesn't seem so..
Irrelevant. Simply because we got the KT and Jagdpanther, that doesn't at all mean that they are the reason the game has shrunk.
We've also gotten the Tu-2, Yak-3, Yak-7B, Me 410, He-111, P-40F, P-40N, B-29, Ki-43, and Ju-87G since the game has started shrinking. Its equally likely they are the ones responsible for killing the game.
