Official News on patch 4.3 and Dragon Soul
World of Warcraft patch 4.3 will offer players the opportunity to take the fight to Wyrmrest Temple and beyond, assisting Thrall and the Dragon Aspects as they seek to bring an end to the Black Dragonflight once and for all. 10- and 25-person raids will get to take on Deathwing himself, with three levels of difficulty to consider and epic gear to claim.
Forged by Deathwing during the War of the Ancients, the Dragon Soul harnessed the power of the other dragonflights, until it was ultimately destroyed. After recovering a version of the artifact from the Caverns of Time, Thrall and the allied dragonflights now rally at Wyrmrest Temple in a desperate bid to use its might to defeat Deathwing.
Created by the titans as a sanctuary for all Dragonkind, the crumbling Wyrmrest Temple is now the final hope for the forces allied against the black dragon Neltharion, once the Earth-Warder and protector of Azeroth, now Deathwing the Destroyer. It is here that the remaining aspects -- Alexstrasza, Ysera, Nozdormu, Kalecgos, and Thrall -- have gathered to empower the Dragon Soul -- Azeroth's last chance to stop the great behemoth. As they begin to charge the Dragon Soul with energy, Deathwing and his entire army assault Wyrmrest Temple. Players must thwart the attacking forces long enough for Thrall to charge the Dragon Soul.
Before you face Deathwing the Destroyer, you must prevail against six mighty bosses.
The most powerful elemental still under Deathwing's sway, Morchok -- once a passive guardian -- is now convinced that his only respite will come with Azeroth's demise. Morchok rages against the foundation of Wyrmrest Temple, Azeroth's last beacon of hope in the Hour of Twilight.
Countless ages ago, Warlord Zon'ozz and his soldiers waged endless war against the forces of C'Thun and Yogg-Saron. Millennia have passed, but the warlord still serves the chaotic might of the Old God N'Zoth. Deathwing has now unleashed this legendary faceless one to crush the defenders of Wyrmrest Temple.
