My second sentence answers your question, "why?" My second sentence was my entire argument.
Well, I'm sorry but I'm suffering a complete comprehension failure. Can you make your argument simpler?
To answer your other question: Your scenario with Sharpshooter looks a little problematic (and rather reinforces zardnaar's position that the feat is broken),
Sharpshooter being broken or not is something for another thread.
and if it concerns Hawk Diesel, I think a decent solution would be to reword Swift Strike to give an extra melee attack,
Or restrict the style to melee attacks only. I still prefer the use of the bonus action.
only . . . which removes the sling from the feat, though. That's a downside.
A sling isn't classed as a light weapon, so would be excluded anyway under my rewording.
It's just occurred to me that the a Close Quarters Shooting style in the UA article about Underdark characters that could make this style totally OP for ranged attacks because it negates the Disadvantage imposed by having an enemy within 5 feet. Sure you need a way of having both styles and the feat, but where there's a will, there's a way.
