General

• The Brood Mother Returns
• After years of lurking in her lair battling the many brave adventurers who travelled from afar to challenge her, Onyxia returns stronger than before to commemorate World of Warcraft's five-year anniversary.
• Onyxia has been scaled to offer new challenges to level 80 players in 10- and 25-player modes.
• Adjusted for modern raiding, but with the fundamental experience of fighting the Brood Mother still in effect, including the horrors of her Deep Breaths!
• Onyxia will now drop level 80 item versions of some classic loot items from the level 60 encounter.
• Brood of Onyxia, a very rare 310%-speed mount modeled after Onyxia herself will be available for the luckiest of challengers.
• Armor Penetration Rating: The amount of armor penetration gained per point of this rating has been reduced by 12%.

PvP

• Battlegrounds
• Players level 11 and higher will now always see a daily Battleground quest, as the quest giver will only offer daily quests for a Battleground in which a player is eligible to participate according to level bracket (i.e. players levels 11-20 will always be offered a Warsong Gulch daily quest, while players levels 11-50 will be offered either an Arathi Basin or a Warsong Gulch daily quest, etc.).
