With ICC and the reduced dodge is this once again a viable enchant? http://www.wowhead.com/?spell=27946 i put it on a backup shield and it gives .91% more block, i know that there is a difference with value and rating. i noticed the site gave 5 pts for the shieldblock enchant and more for value. which is the better enchant? it seems that combining this with something like http://www.wowhead.com/?item=50290 would be pretty good when trying to build up a bit more block for icc
I push over 600 defense in my avoidance gear and yes 20 defense is still the better avoidance enchant despite diminishing returns. you're still gaining miss, dodge, parry, and block. defense is the best avoidance stat if you are including block with avoidance. the amount of defense needed to outweigh the amount of shield block given is not reasonable to reach. no one is going to gem pure defense.
