I do not believe there is any malice. From my interpretation of Ghostcrawler, they simply have no idea what they're doing with Shaman.

Elemental is not highly played, and they seemingly prioritized it as such. First they claim that damage is "fine" for a month or so, then "oh its bad but wait for newamazingtalent" and "we know its bad but we're not balancing you at 70".

It really does seem that they've "gone back to the drawing board" with shaman, and that means we'll be in limbo(in an underpowered state, unfortunately) until they figure out how our class is going to work. They certainly seemed to have repositioned themselves publicly on how they present the shaman class is supposed to work several times, and admitted major "miscalculations". It may even be by design(for scheduling purposes, not malice) that they balance the least played spec/class late, by depending on a talent is only available till after launch.
