imo, the wind will not only affects the ballistic projectile from ships, but also the aircraft flying direction. for my addition to make the battle feel more real, maybe it'll be good to add weather condition to the game, since not all battle are happening in bright, sunny weather.
sometimes it happened in a middle of storm, in a misty night, in a light rain, in a high sea current, or even in a snowy day.
all of these types of weather of course will affect the battle, ship condition, ballistics and its projectiles.
however, I realize that to make all of this is not a simple feat.
