We recognize that many plate tanks are making their gear choices based on the amount of armor they’re provided, as this is currently the most preferred stat. In order to make the tier-10 plate tanking sets more desirable, we will be adjusting the stats on the gloves and chest pieces in order to inflate the amount of armor they provide in the next minor patch. This will apply to all item levels of the tier-10 death knight, warrior, and paladin tanking gloves and chest pieces.

Similar items crafted or purchased with Emblems of Frost will continue to be very good and will compare favorably to all but the Heroic difficulty boss loot, so you shouldn’t despair if you recently acquired any of those.

• Different items will lose different defensive stats (parry, dodge, defense, etc.) to compensate for the bonus armor being added.

• We are concerned that Feral druid tank gear won’t scale as well and will be keeping an eye on it.
