This may seem like an obvious question, but I have a question about Guided Arrow. Because it "always hits", is there a point in pumping your attack rating at all? I know that with Freezing Arrow, AR will matter because the actual arrow itself will do damage as well as the cold, but I don't know how that works with Guided Arrow.

The reason I ask is that I am going to be making a PvP Guided Arrow amazon, and I don't know whether or not I should invest in Penetrate.

Thanks in advance for any advice!
