We have recently updated our Talent guide for the Rogue in WoW. The new information contains the changes made to the Rogue with patch 3.1 and includes all three schools.

There are three different schools that a Rogue can choose from when making their build: Assassination, Combat, and Subtlety. Each school focuses on inflicting the most damage, but through differing methods. The Assassination school specializes in doing burst damage and getting as many combo points as possible as quickly as possible. The Combat school focuses on regular, sustained DPS over the course of the combat. The Subtlety school emphasizes speed and stealth while getting the most combo points possible on the opening shot.
