Cataclysm Systems Patch World of Warcraft: Cataclysm will be in stores on December 7, 2010 and the time has come to prep for the official launch by implementing its first major patch. Players can experience many major game and user interface systems updates in the first official patch for the upcoming third expansion, patch 4.0.1. General Cataclysm Launcher Update The new Cataclysm Launcher allows you to stream game data while you play.

Any dungeon or raid which awarded these emblems will reward Justice Points instead.

Any bosses players defeat that are level-appropriate to them award Justice Points. All items that previously cost emblems or badges of any type now cost Justice Points. Higher-tier Valor Points will be awarded to players who kill dungeon and raid bosses in the latest tier of PvE content after the launch of Cataclysm.

Ammo has been removed from the game.

The character levels at which classes gain new spells and abilities have changed.

Many item and class stats have been changed or removed.

Talent trees have been altered. All player talent specializations have been reset, allowing for free re-specialization. Each specialization has been reduced to a 31-point talent tree. Players will now get a total of 41 talent points to spend. Players will be asked to choose a specialization at level 10. Doing so will result in the unlocking of a spell or ability unique to that specialization, as well as one or more passive bonuses. Once a talent specialization has been chosen, players may only place points in the primary tree until at least 31 points have been spent there. The initial announcement regarding these talent tree changes can be found on our Cataclysm forum: Cataclysm Class & Mastery Systems Update
