Gnomeregan auto blocker vs Shard of Contempt

[Brainwreck]

Overall which one would boost my threat most?

Pretty sure Shard without a doubt.

Shard for single target
Autoblocker for AoE (aslong as you have damage shield)

[Valdur]

I'm usually using Autoblocker for most cases. It's good for AoE tanking and as well as single target tanking. Just pop your autoblocker followed by shield block so your shield block value is high and start spamming Shield Slam. Got about 5-6k crits with it and it does add a nice amount of threat.

I'm a big fan of the two Block Value trinkets. I've been messing around with gear and seeing how big I can get a Shield Slam, and so far I'm up to 11k against a no-armor target with Imp Disarm and Impale. Nowhere near the best, I'm sure, but I'm pretty pumped that I can throw 11k Shield Slams out there.
