I did that w/ light shot also, use a PS3 controller, so moving back and forth between every shot isn't really the most efficient method. I also use very few macros on arc/brd for now, I haven't hit 50 yet, maybe I'll use more then. For now though using a /shot /wait /shot for 5 shots per press is decent, it's almost an AA.

This whole bit w/ DPS being the important stat is incredibly counter-intuitive, maybe that's just because of years of the base dmg value being the most important in XI, but I'll adapt.
