Ah, because I'm weird...
My barbarian was really a barbarian/fighter and he actually dabbled at intimitanking.. 90% of the time he was pure raging DPS, but he did tank in VoD and Hound and even Shroud way back when holding the devil was useful.
I did actually build a +6 CHA skills Shroud item for him... (or maybe it's +5... It has disease immunity and blindness immunity and +6 wisdom).
Chattering ring I don't have yet (even though I did 20 titans in my last reincarnation). I might go for it again...
You can actually get a decent AC on a barbarian/fighter... enough to tank most raids on normal...
And when I rebuild him he'll probably be 18/2 barbarian/fighter and I'll still want to handle minor tanking roles (I PUG a lot, and you'd be surprised how often he actually had the best intimidate or AC in the group).
You are right though that the SD set might be a waste - I'll try not to roll on that against any other SD, since this character may not be permanent.
(There IS a chance that I'll keep this guy as a fighter, though)
