Unless I misunderstand you and by automated means you mean "really easy to farm" and not "afk while a program does it for me" - but I am not so sure you meant the former.

My official stance (and unofficial one as well) is that trying to automate gameplay will more than likely get you banned from WoW. There are ways to do it but the effort hardly seems worth the investment. We box here for fun and as a hobby and these forums are not the place to discuss automated game play or botting of any kind.

So if you are going to do it - don't come here and ask for advice. Take it to WoWGlider or wherever else you wish.
