I would be interested to hear more about this.
As to the ghost hawk being OP, we have very clear, strict rules about using the guns. Even when the go ahead has been given the chances of shooting to a helicopter that is being piloted by someone with more than 10 minutes flight experience is slim at best. Shooting down a good pilot is near impossible. All you have to do is figure out which side has a gunner then just bank any time the Ghost Hawk tries to line up a shot, anything over 300m or so and the shot accuracy drops to nothing. There is so many variables to utilizing the ghost hawk to its full potential. The only time the ghost hawk can be considered op is if someone shoots at it from the ground, hitting a stationary target is so simple even Pinkstreak can do it!
Another thing i always read about is the cop tazer being op. I agree to a point. one leg/arm shot shouldn't be enough to taze someone, that said though the fact that pretty much ever life server uses this taze script I would imagine cause there simply isn't a better way to do it. The only alternative is giving cops lethals and i'm sure nobody wants that.
