The reason this could be better for ARC is because it will help you keep up with standard attack DPS output. It keeps your TP going so you can worry about other things.

And I'd be less worried about AA and more happy about ARC (hopefully) becoming a viable DD option to play again. I know at least 10 people who used to play ARC who were forced into playing LNC and don't even play anymore because ARC is at the current moment not as effective as the other DD classes.

Let's be honest, hitting 1 over and over isn't -actually- interesting, but hopefully with the class changes it will make the Archer itself more of a fun class. Especially in the future when you will be playing songs for party members, which will probably have you all over the battlefield.
