Bots are generally considered not to be near the full effectiveness of a main. Since less attention is paid to them they need differnt AA paths. As an example when I am botting (95%) of the time, I don't hit Pained Memory every 18 seconds, I am lucky to hit it every other mob. So for me Expansive Mind was a very imporntat AA, moreso even then Spirital Channeling.
I tend to focus my bot on what will help my tank, for example Crits on HoT, Longer buffs, Quick buffs (so Spiritual Serenity goes off faster), spell casting subtelty. Last weekend when I played my shaman in Skylance 1-3, as a shaman not as a bot, I discovered that the Defensive AA which I ignored since I rarely got aggro as a bot caem and bit me in the rear. As a bot Defensive AA was nto important, as a single toon it is.
What AA do people consider necesarry for a bot? That might not be as needed if you were playing just a shaman.
(Expansive mind is in this category for me)
