Caught this on a random visit to one of my old World of Warcraft stomping grounds. This is from the patch notes for WoW 3.2.2.
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 to commemorate World of Warcraft’s five-year anniversary.
Onyxia has been scaled to offer new challenges to level 80 players and is now available for testing in 10- and 25- player modes.
Adjustments have been made to the encounter to keep it fit for modern raiding, but the fundamental experience of fighting the Brood Mother will remain, as will the horror of the Deep Breaths!
Some classic items Onyxia offered level 60 players will have their stats adjusted appropriately for level 80 players.
Brood of Onyxia, a very rare 310%-speed mount modeled after Onyxia herself will be available for the luckiest of challengers.
Now they catch on that there's value in older content. Too bad they didn't figure this out ages ago before we all got bored and left. Of course, their idea of "adjustments made to keep it fit for modern raiding" might include Ony crapping epics and then fleeing in fear when she sees a typical raiding party. That would certainly fit Blizz's faceroll-to-victory design paradigm.
