There's a general problem on the show with the incredible accuracy of bows overall. Last episode we got a scene where Arya shooting a wight threatening Sandor was treated as an amazing shot. But was it really?
Jamie's archers were able to hit a flying dragon. Theon was shooting ravens out of the air at the Twins. Ramsay just generally. All of those are elite archers, but have we actually seen anyone doing badly with a bow? Aside from Edmure, which was played for laughs.
I had the same issue with the Hobbit movies. In Lord of the Rings Legolas's accuracy is at least played as being exceptional, but during the scenes like the barrel-run battle, both elves and dwarves manage ridiculous shots and moves routinely enough that they coordinate them with each other in the full expectation of being able to pull them off 100% reliably, and Bard is considered a failure by the folks of Laketown for having been unable to hit a fast-moving dragon in a firestorm using a fixed-emplacement ballista.
