There is one, and only one, reason why a hunter should ever roll on this item. Caster interrupt in battlegrounds. It's a strategy that isn't used very much because it drops DPS dramatically. But, theoretically anyway, The UBER fast shot speed and a BM\MM spec might be able to put out so many arrows that spells can be massively delayed. In practice though, caster talents that reduce dmg interrupts make this pretty much null and void. Any BM hunter at this point should be sticking to the Wolfslayer Rifle or Barrel Bladed Longrifle.

So, in a roundabout way, hunters should never have this item.
