I came up with a stun barbarian build myself, and while it looks really cool on paper I started to wonder what in the world it will do if it gets camped by any amount of other barbarians. So long as one barbarian can stay on top of you and mess with you even a little you'd just be out damaged, out buffed, out debuffed and if you tried using your stuns as utility I'd imagine the other barb would heal like freaking crazy from what will soon basically be required before queing up for pvp, Juggernaut. Stuns are going to have reduced duration, juggernaut is going to reduce it further, and you're going to get your sht pushed in by other barbs.
Edit: To see more of my ideas for pvp barb, I suggest browsing this topic in which I have many different, unique ideas for barb builds. I'd say the theory will explain itself per each build, as each is designed to handle different challenges.
