It's not bad, but like Pedobear said, I disagree with a lot of the stuff there. I see no reason why to NOT add to DEX. We're not talking about being able to be missed, we're talking about aim. With my experience with talking to higher-leveled people, both inside and outside my guild, they mostly grind on red mobs. With DEX, you get to have extra aim, added with maybe the aim scroll that you use.
I also disagree with the order of shooting. You should use your poisons first (Fury impact and Bone Shot), as they have the same distance as Aimed Shot. That way, the DoT kicks in earlier than if you use Aimed Shot first. I agree with using Power Shot last, since it is the least-ranged skill.
I also agree with Pedobear on spreading into 3 stats. It's going to make it a little weak, the advantages little.
However, I agree with your production skills. ;O I wish I knew that when I first started, as it seems convenient to have scroll and pots on a character.
I disagree with Pedobear on SP usage. It isn't useless at all - in a good party, I go through a ton of stones/pots. SP usage helps with that a lot, but I'm not saying that cooldown is useless. Both have thier own usages.
It's a good first guide though =) I'm sure it'll help a lot of archers out there.
