I am getting weird talent bugs on my 5 shaman. The other day I couldn't place points in my talent tree, I had points available but clicking in the tree just didn't do anything. I switched on the planning mode and then it seemed to work, I could allocate the points and confirm to actually spend the points. Then I noticed today the points were available again. Don't know if it is related to the shaman dps problem but something is definitely very fishy with shaman talents.
