If you like tanking (sure, we all do) you may be interest in this update to yesterday's post about tier 10 tanking gear: the dodge on gloves and defense on chests is being removed and the armor is being increased to bring them in line with the off-set tanking pieces due to the popularity of higher armor in Icecrown Citadel, and we now finally have hard numbers. So far, it looks as if the armor increases are pretty significant (882 armor on iLevel 251 gloves, 1064 armor on iLevel 251 set chestplates) and should make up for the dodge or defense lost, especially as armor has increased in popularity due to the Chill of the Throne debuff in ICC. We're told that the armor increase scales with iLevel so the iLevel 264 and 277 versions will also have proportionate armor increases. This is a patch 3.3.2 change so don't panic if your gear doesn't have the armor yet.
This makes me even more happy that I chose to focus on my tier set over offset pieces to get the four piece bonus as soon as possible. It makes these pieces far more attractive when compared to the high armor offset Cataclysm Chestguard and Gauntlers of the Kraken. (the Sanctified 264 versions should have exactly the same armor). I'd like to have seen a little more armor on the pieces, myself, but it's still pretty solid.
