In a surprise move that's incredibly welcome (well, in my eyes) Blizzard has gone back and changed Paladin and Warrior tanking tier 4 to 6 gear as well as non set plate drops, shield and badge gear to take advantage of the new mechanics. As I primarily am a tank (and expect to remain so) I went online to check out how my tanking gear will change when patch 3.0 drops. A gallery of some select pieces and how they're changing when patch 3.0 goes live has been provided for all your browsing needs. I have to say that for the most part the changes are very welcome, they maintain old block value for threat while adding the strength we'll need for increased AP to scale our new threat abilities like Shockwave.
Take a look at the changes to date. (And thanks to MMO-Champion for the head's up.)
