Everything you mentioned there is true. Hell, a shotgun is the only thing I could defeat an Mp40 with, and even then, it to be luck. Even with a PTRS-41 at massive range, they still kill me! DX<
Some more things you could've hated were the tank's driving and reloading speed being way too slow, even by real life WWII tank stats, and also, snipers when you're on a tank's machine gun.
