World of Warcraft v2.3.0 German Patch

* The latest patch of World of Warcraft: The Burning Crusade shows a benefit on today's popular multicore processors like the Intel(r) Core(tm)2 Duo processor family. The enhanced patch has demonstrated higher frame rates by spreading the work across both processor cores.
* Zul'Aman is a 10-player, level 70 outdoor instance located in the Ghostlands. Players will be able to confront six new bosses including the Forest Troll Warlord Zul'jin.
* Guild Banks have been introduced. The Guild Bank will allow players with the appropriate permissions to store items and money for use by the rest of the guild.
* Experience: The amount of experience needed to gain a level has been decreased between levels 20 and 60. In addition, the amount of experience granted by quests has been increased between levels 30 and 60.
* All items have had their bonuses to Weapon Skill Rating converted to a new stat called Weapon Expertise Rating. Each point of Weapon Expertise reduces the chance for your attacks to be dodged or parried by .25%.
* Healing reduction effects will now affect all health drain spells and abilities (e.g. Mortal Strike will reduce health gained from Drain Life).
* Healing: Almost all items and enchantments that provide bonus healing now also provide a smaller number (approximately 1/3) of bonus spell damage. There are a few items and enchantments where this was not possible, such as random-stat items and Zul'Gurub enchantments, but this is now the case on virtually all other items.
