I can imagine. Headshotting with arrows are really awesome.
Yup. Also, when you KO someone in Dissidia, there's a slow-motion shot of the enemy being hit, then a slow-motion shot of the winning character. When Firion KOs someone with Straightarrow, the slow-motion shot of him shows him slinging his bow back over his shoulder in a rather cool way.
It's kinda like when you win a match in Metroid Prime: Hunters with the Imperialist.
