Patch 1.0.3 Coming Soon.
Patch 1.0.3 is in the works but the gaming community is still waiting for some official data regarding the incoming changes. It seems that the patch is on the servers but it is not available for download. Some of the changes were datamined showing a few changes for tooltips and PvP icons.
The Barbarian will have one significant change to his skills while the rest represent just a tooltip correction. His Overpower skill will not redirect ranged attacks as well.
For Demon Hunters, the Cluster Grenade will also change the damage type to physical and Wizard Star Pact rune for the Meteor skill will now change it to Arcane.
Other than that there are some minor rewording of existing skills for Monks, Barbarians and Demon Hunters. There was no data mined for the other classes but odds are that the patch is still a work in progress.
For the PvP aspect of the game, some buff icons were added. There are also some new banners for the upcoming World of Warcraft expansion, Mists of Pandaria. Other from these achievements and skill changes, we should expect a nerf of the attack speed bonus of rings, gloves, amulets and weapons.
Blizzard decided to reduce the maximum bonus and the existing weapons will be nerfed by reducing the percentage of the increased attack speed significantly by at least 50% for the highest values.
Last but not least, all exalted recipes had their gold crafting costs reduced by a bit over 50% and the materials required by around 30%. There is no data for the leveling cost of the Blacksmith but the Jeweler had its prices cut and the crafting materials needed downgraded from three to two.
More details should become available as the dataminers explore the game files. However, we should expect a Blizzard post revealing these changes very soon.
