Hmm, interesting that you guys are saying the defense is better. I'd like to put up an argument for the block value.
BV is one of the best threat stats we have; second highest threat stat on single targets. Defense is not a good offensive stat. >_>
The threat charts.
That's a threat standpoint. Mitigation wise, .48% avoidance and .16% block pre-DR, versus 52 post-talent block? It's block value, so the obvious answer is that "it depends on how hard you're getting hit."
Let's pretend there's no DR, and the block rating is a perfect avoidance, tipping the scales drastically toward the Def enchant. 52 / 0.64% should give the point where the avoidance equalizes with the BR's reduction, ignoring the fact that BR means less spiky damage. ATTD or whatever it's called. It's at exactly 8,125 damage. (Edited: This is incorrect, read the later post)
So as long as you're uncrittable, block capped, and taking hits for 8k or less, the block rating seems very much superior. It'd be really messy to figure out the math for non-block capped tanks, but the numbers are similar if you're close to the cap.
Of course, if you need the Defense for uncrittable, this is a good place for it. I'd prefer gems though.
