People praying for 4th specs: can you tell me what makes you think there's even a remotely good chance of it happening?
They gave warrior 4th spec, then took it away. Why? It didn't work? They didn't bother with balancing it all the time since it worked with tank gear. Personally, I liked it a lot. They had to rework bunch of specs such as Combat and Survival to even justify some classes having 3 specs, let alone 4. For DH they straight up didn't even bother coming up with a third.
Just not happening.
