Gunnery Skills

I <strong>really</strong> don't get why you need to have a level 5 projectile weapons skill to get a level 1 rocket gunnery skill. How is firing a Auto Rifle going to help you shoot huge torpedoes or lay mines etc.  I think that players should either have to have to have a level 6 gyro-jet weapons or a level 5 gyro-jet and level 4 demolitions skill.  Slightly off topic: couldn't intercept missiles be aimed by a gunner for more affect?
