Most likely a fake image...
But lets look at the 2 classes i play...
- Warrior, the new spec resembles a shout, i see a dragon shouting. Warrior's use shouts (commanding shout and battle shaout) for buffing, for cc (fear). Having a drongon resembles me fire wich might be able to indicate some kind of ranged intelect plate based spec.
- For shaman's its even worst, earth shock?? If they used frost shock icon then it would be obvious, a new tanking spec... But earth shock, i see a spec based around the strenght of earth, wich leads me to tanking again.
