I just think it would be neat to shoot someone with an arrow, then do the Assassin's Creed chain assassination animation.
You know, the one where you quickly close the gap to the person you just impaled from range, rip the knife (arrow) out of them and then immediately throw it at the closest enemy's head.
Or an alt fire for a bow where instead of doing a rain of arrows you just start spamming arrows out of your quiver by hand like they're shuriken.
Something cool worth building into because it's flashy and effective.
