In the Cataclysmic long term, this stat will be going away as the way things will be handled will be by combining block rating and block value into one stat. It will be more like block rating than block value, but it's better to think in the terms of a new stat since it will work in different values than what players are currently used to seeing in block rating.
For the short term, we just stopped itemizing it because it’s generally not a very attractive tanking stat except in very specific cases. I give a /wave to those Anub'arak’s adds tanks out there. In the current content the chance to prevent a small amount of damage isn’t worth the budget, nor do we really want tanks to be at that 100% chance to block.
