World of Warcraft's fifth expansion pack Warlords of Draenor will release on Thursday, November 13, Blizzard announced

The new expansion introduces a "world's worth of content" to the 10-year old MMO, letting players fight for control over PvP zone Ashran and manage their own garrison, a new upgradeable fortress that players will be able to customise and build throughout their journey.
The expansion will also raise the level cap from 90 to 100, with new dungeons, raids, challenge modes, battlegrounds and more promised, too,
"Players will encounter an epic cast of legendary characters and a huge amount of content to explore in Warlords of Draenor," said Blizzard CEO Mike Morhaime. "The countdown to the arrival of one of the greatest threats in Warcraft history has begun. We can’t wait to send everyone through the Dark Portal this November."
