im not sure warchief is the right title for him, from my knowledge (i could be way off) didn't he almost join the alliance again at some point? not sure thats what we want in a warchief. He's level headed and a great tactition yes, but i would rather have Vol'jin sit as warchief. While being a level headed and great tactition he has also been with the horde for quite a long time and has some strong friendships within the horde such as with Baine Bloodhoof
