Thorkou
If I run for wherever I see lightning striking, I still never got more than 350 ward. Lightning never targets me; I have to run where it is already striking. I assumed that if I wear all 3 items in the set (which I do), the totem would also target me in addition to mobs in the area, but it never does.
Scouring the Storm Totem nodes to make sure I didn't spec something that would affect this, I found nothing relevant. I'm pretty much giving up on this build since it does not work for me. For now I'm focusing on trying out Falconer and Warlock. Shaman is such a neglected and undertuned mastery now.
