Before you even take into account what class to use it on, you have to look at the fact that it's 100% useless solo, very likely to be useless in a 5 man/10man (if you don't have anyone of a certain class in your group/raid).
Additionally, as much empahsis as they've put on the "active mitigation" model. Every GC is important for generating rage first and foremost.
With boneshield, the 10% reduction is so weak with the nerfed charges, I wouldn't be surprised to see parses/sims showing that you're probably going to be better off not using it when in combat and taking damage, and instead, hitting mangle (to generate rage), refreshing thrash, lacerate, or FF.
Also, it's going to be much more useful to use only after you have SD up (otherwise the first 3 swings will probably take all 3 charges). Basically, you'll have to be in a situation where you don't need to do any of those (which is going to be extremely rare).
The only other abilities you'd even remotely might want to use as a tank (due it triggering a GC) are consecration and frost trap.
Consecration has the same weakness as Boneshield (triggering a GC). It's so weak it's a waste if you are already in combat with a mob on you to tank. It's only worthwhile if you drop it when you have nothing to do at the moment and you need to pick up adds at one spot...but need to move to another spot...Otherwise you are much better off hitting Thrash or Swipe.
Frost trap is only really helpful if you're with a lazy pug hunter that won't drop their own if you need it.
Compare the other 87 abilities (tanks or otherwise) get. This is an absolute joke compared to the DK or Warrior abilities.
