* Bloodrage - Fixed a bug that caused Bloodrage to cost twice the intended health
* Sweeping Strikes: This spell has a number of fixes: When used in conjunction with Execute and the second victim is below 20% health, they will be hit with the full Execute amount. If the second victim is not below 20% health, they will be hit with normal melee swing damage; If the ability you are using does not deal damage, it will not use a charge of Sweeping Strikes; The extra attack it generates when used with Whirlwind now has the correct damage range; The additional attacks generated by this ability will now properly take into account the armor of the second target.

* We have re-evaluated the mechanics of consumable items in the game and concluded that these should work in a more intuitive manner. As such, most items that can not be equipped with right click abilities have been streamlined into one of three categories. Using an item of a particular category will trigger a shared cooldown among all other items in the same category. The categories break down as follows with category cooldowns as listed.
o Potions 2 minutes: This includes items such as Health Potion, Mana Potion, Invisibility Potion and Mighty Rage Potion.

o Non-Aggresive 2 minutes: This includes items such as Healthstone, Night Dragon's Breath, Whipper Root Tuber and Target Dummy.
* Many items that can be equipped have had their cooldown category removed and will be controlled exclusively by the item's self cooldown. For example, the Gnomish Mind Control Cap should no longer trigger the cooldown of the Talisman of Arathor.
* We have re-evauluated the class specific quest rewards for both Zul'Gurub and Ahn'Qiraj Ruins. To bring them more in line with the effort required to attain them we have upgraded the superior items to epic quality.
