Gunnery works well on monsters that are difficult to get close to without being hit, or have hard skin. Like Fatalis.

I think gunning things, especcially fast monsters, is really hard. As Syntarus said, so many thinks give 1HKO its silly. If a monster decides to go for you as a gunner, you run like hell.
