I have archer as a sub, but actually started as one. I switched due to the lackluster animations and the atrocious sound effects. I mean, firing an arrow sounded like a robot DJ dropping his duke box. Ironically, my second class was Conj. whose SFX were worse.

I do like the idea of fletching colors, and trails to show the path of the arrow (or even just seeing the arrow nooked instead of a ball of light). But this is a FF world, where flashy lights and robot sounds rule. Good suggestions, though. I liked a lot of them.
