Yes you can do that. But is that good? Not in the slightest bit. You've essentially wasted action points because you will be outperformed by every other Archer that is boosting their attack by using their points to get abilities that do that from other classes as opposed to a spell they wont ever use.
Ahh I see, thats why we're not on the same page. I'm a person that encourages people to do their job and perform well at it. I'm a min-maxer, an FFXI BG poster, a WoW Elitist Jerks poster - you on the other hand are the type that plays what you want regardless of whether or not its good.
We will never agree. So I give up.
