Actually, the real Chuck Norris of the Horde always was High Overlord Varok Saurfang. Check the link and there you have it. This was going on when Chuck Norris jokes were all the rage, the internet and tv had Chuck, we had Saurfang.
I haven't, Varok Saurfang is a bigger Badass in the Fighting Department. but Thrall makes up for it in the Honor and Mind Department. Varok may acknowledge his mistakes and attempt to make amends but unfortunately the guy just falls short of that area. so I have painstakingly tabulated their feats and losses. I can confirm. they are Equal in the Art of Badassery.
