Il nome dell'espansione è "Rise Of The Naga Empire" e vede l'arrivo della fazione dei Naga nel mondo di gioco, come una potenza neutrale con cui fare i conti.
Qui di seguito l'incipit della Trama dell'espansione:
Tale espansione dovrebbe inoltre portare il livello massimo al 120, otto nuove zone da esplorare, una nuova arena, due nuovi campi da battaglia, dodici nuovi dungeon e tre nuove zone per i Raid.The Burning Legion has diverted the attention of the heroes of Azeroth away from their home lands. As the war wages on Argus to stop the Legion, Azshara continues her preparations in carrying out the will of N’zoth by readying an invasion that will cover every continent on the planet. The Naga Empire has been building its forces and patiently waiting for the perfect time to strike. Using a twisted form of black magic and power granted to her from N’Zoth, Azshara will carry out a ritual that will cause the submerged Naga empire to rise from the depths. Both the Horde and Alliance are unprepared for such an attack, and as a result, many iconic locations will be destroyed. In order to defend the lands that the factions of Azeroth hold dear, both major factions must band together even amid the hatred both feel for each other.
Inventions created by the Gnomes and adopted by the Goblins will be created and refined to help curtail the invading Naga. Gifted and mechanically intelligent Gnomes and Goblins will pilot massive suites of Armor and will be instrumental in holding off the Naga invasions. These Tinkers will be looked at by the rest of the horde and alliance as essential to the military efforts that will greatly help turn the tide of battle.
Sarà inoltre aggiunte la nuova classe "The Tinker", e i giocatori potranno usare come cavalcature delle Barche, che saranno personalizzabili da parte dei giocatori stessi,
