1.10 Armor Set Quests

[Luminon]

From http://www.worldofwar.net/patches/preview/1-10.php

We've been making a number of improvements to item drop rates in Stratholme, Scholomance, Upper Black Rock Spire, Lower Black Rock Spire, and Black Rock Depths. In the next patch, the drop rate for many items will improve. In some situations, we will even be improving the quality of select items found in these dungeons.

Beyond this, we're also adding several new items to existing bosses, and even to new bosses which will be available at various locations throughout these instances. Many of the new items will offer statistical improvement with certain classes in mind, such as rings which offer both spell and melee crit, ideal for the Paladin, Shaman and Druid.

A brand new eight piece dungeon set will also be scattered through the locations outlined above. This set, available only to the Warlock, Mage and Priest will offer a substantial amount of armor, hit points and intelligence, making it great for PvP. Below is an example of the set:

Ironweave Robe

219 Armor
+24 STA
+15 INT
Durability 80/80
Classes: Priest, Mage, Warlock
Requires level 58
Set bonuses:
(4) Increases your chance to resist Silence and Interrupt effects by 10%.
(8) +200 Armor.

(emphasis mine)

I'm really impressed with what they're doing with itemization this patch :), especially for hybrids and cloth wearers; who are sorely in need of it.
