o found it better then the other shield in my case i also have Crest of Sha'tar just for the reasion i get better tanking stats then Dawnforged.

Ps. I think bliz did a great job with this shield. the def between the 2 shields are:
dodge/block= Pally aggro is also Passive so u want to take a few hits.
spell hit/melee hit= well all a pally tank dose is use spell to do most of his agrro pulling

Spell dmg/ block value. ok id u want more block then go with the sha'tar shield cram a few hp gems and your good. to go.
