I think it does, and I think dropping WC for Stomp to Stun a mass of mobs into an Oculus bubble is going to be the best DPS option. At least until they all go CC immune from the Frenzy Stuns, which will only take a few seconds. 
I do think the build will be competitive with Pro-Slam, maybe slightly stronger, and if that’s the case, cool. It doesn’t really stand out, but it won’t be total garbage, and Blizzard has expressed a willingness to re-tune if necessary.
I’ve got too much on my plate as it is, so I’m trying to twist Rage’s arm so he’ll write the guide. Maybe if you all twist with me, we can convince him.
What do you say, Rage? 
The easiest way to get around this is to get Freeze on hit on either belt or weapon, then use Parthans as your bracer. It will make you much harder to kill.
All in all, I think the devs played it too conservatively with this set, and they were clearly not willing to address the major problem: the 2-piece bonus neutralizes itself due to a Frenzy rune granted by Undisputed Champion. This is still a bit of a WTF set, but for Barbs who have long wanted Frenzy to be competitive with other builds, well, you got your wish, and it is fun to play.
