Shields: wtf is up with these? All armor giving n stuff

Ok, I have always wondered this. Perhaps someone can supply me with an answer.

Why does Blizzard put +block value on shields? They have this on many, many tanking shields in the game. Example:

Shield of Impenetrable Darkness
122 Block
Equip: Increases the block value of your shield by 33.

Why not just say "155 Block"?

Please enter your typed, double spaced answers below this sig:

I think it works like this:

The block value is related to the armor, meaning that there's some math that gives the BV from the armor.
If you check, shields with same armor have same Block Value.

Now, if they want to add BV to a shield without having to increase the armor, the only way to do is the "Equip" effect.

I believe that the core block value scales directly with the item level, while the added stats are made up from the item budget for an item of that level

Yet, the above comments would apply to armor, which is instead listed as "green" on those items with additional armor above their iLvl/armor class instead of having the extra armor as Equip:. It would make sense to do the same for block value imo.

As worldie said, it's an "item level determines armor and block value" thing.

Now that you mention it, though, they probably should put bonus armor as a separate mod, too... feral gear and the felsteel set are prime examples of gear with "extra" armor on them. Wouldn't it make more sense to have a "+184 armor" modifier instead of just making the number green? Basically the opposite of what Alacia said.
