We're BORED. We can't languish like this until End of Dragons. Honestly please push back the expansion and make a good balance patch first. Don't just let the game fester and ignore it whilst you power-develop the elite specs.
Right now, you have put every skills/balance dev to work on the new spec and left them with 20 minutes at the end of each two months to assemble a smattering of changes. Slow down the expansion and make sure a good patch or two gets out the door first.
