I forgot I posted here. Long story short, increasing DEX increased the damage of Light Shot. I used the parser that Carraway linked here (thanks for that btw!) to come to that conclusion. Now as far as Foeseeker or weaponskill damage in general... that I haven't extensively tested yet. I would assume at this point you would at least want Attack Power to a point. I have +19ATK on my hands but I'm not sure if that's enough to see anything noticeable. I can play around with that too though... no harm done in that.
