Yeah, it's been pissing me off too with it's "lazer" accuracy.
One time I was bombing a strat that was pretty much dug into a range of mountains when I ran out of ord. So I decided to return home and land the plane. But to return home I had to climb out over the mountains infront of me. So I gained some alt. The whole time puffy ack shooting near me.
I figured the best way to stop them from shooting me was to descend right after I flew over the top of the mountain. So I made it over and started to loose alt. Too my surprise the ack was still shooting at me! And with "lazer" accuracy. I mean, it was right next to me... So I thought to myself... Self, how is this possible? Unless the rounds are going THROUGH the mountain it's not. They would have to have the round go over the mountain and dive back down to hit me....
Maybe they have mortar ack?
So I think there needs to be some fixing also.
