I confess I don't have a good feel for how much of our damage is from auto-attacks. It must vary with the boss. Ozruk, for example, hits for almost nothing and then BAM nails you with his specials. Trash mobs are probably mostly auto-attacks.
What I'm seeing is a choice between
A) Always-on +10% block PLUS spell block PLUS passive 75%AP damage to everyone you block
B) AoE attack every 4 seconds that reduces one auto-attack per attacker by 15%
C) Spamming Hammer of the Righteous every GCD with 8 yard radius AoE, and not having to worry about Consecration when you're kiting a boss, moving out of fire, etc.
Every 4 seconds for Blessed Hammer sounds pretty good. If you're taking Consecrated Ground at Tier 90, you're gonna want to drop Consecration and stay in it anyway. And there's probably plenty of other things worth doing between those 4 second casts.
Consecrated Hammer sounds like easy mode when you're constantly moving and kiting. Forget Consecration, forget Blessed Hammer, just bam-bam-spam HoR every GCD for AoE tanking and know you'll also get buffed LoP and SoR whenever you need them.
Holy Shield might be the best of the three for progression, imho. Completely passive, so you can focus on fight mechanics. Blocking spells is huge, the 10% block is significant, and having a pack of trash taking 75% AP damage every time you block them should add up.
A lot of you have had a chance to actually test these. I'm just going by what I read. Blessed Hammer sounds like the shiny new option that's fun to play with, but it looks like they did a pretty good job of balancing the three options on this tier.

Hmmm... If Blessed Hammer replaces Hammer of the Righteous, doing 85% AP AoE damage, while HoR would have done 125% ST+75% AoE...
Then add in that with Consecrated Hammer you could use HoR faster than Blessed Hammer...

Maybe I'm missing something - please correct me - but how is Blessed Hammer not a DPS loss on single target? You lose HoR which would have done 125%AP to primary target and replace it with a spell that does 85%AP.
