Will be from Il-2 drivers upset when they fly level for five minutes, getting boom and zoomed by 10 different aircraft continuously, and GET SHOT DOWN :-)
Going to be an interesting arena dynamic. I suspect the changes to armor rules will make Osties more vulnerable to everything, but make it very hard to kill tanks without a Yak-9T or Il-2.
But I have a feeling that the Sturmovik drivers have wild fantasies of an almost invulnerable AC that won't come true, and there will be massive complaints about it being too vulnerable.
Just my hunch, but I suspect the odds that it's the OTHER way..that people will be whining because it's too hard to shoot down...are pretty low.
Guess we'll find out :-)
