From what I remember there were a couple blue posts saying that Thrall would become war chief again and Garrosh does become 'corrupted'. The revamp of RFC suggests demonic forces might be behind it and could tie it to the next xpac. What I want to know is what is the plan for org in 5.x. Is it going to be hospitable when siege is the current raid tier and beyond? I don't know if they want to go for another CoT raid entrance or not.
