The laser designators aren't that great, which is why they removed them. All they would do is pretty much put a lockon area on the designated target, and thats it. The bombers can still do as they wish, dropping bombs, etc. Its just an extra thing, that, like the assault blackhawk, never had much of a use, or just wasn't used at all.
well it helps alot of you always miss by like a few yards, you gotta practice though. for the n00bies, dont ever drop the bombs when the place you planned to attack is right under you lol, it wont get noone. you have to drop them like a few yards before. it also matters how high your in the air. the higher, the farther away you gotta drop them.
