Is that why he let the shaman torture the elements? So that when Thrall would face him he would find no help in the elements? I really have to say, if he planned that far ahead, that's really remarkable.
Also, it was really fun to see everybody in the raid wait until their speech was finished. I don't know if you have to wait anyway, but it really looked as if everyone in the raid was watching the scene intently. And everybody made /cheer and /wave emotes to Thrall. And I played Alliance.
