He almost did! But he didn't. Our progress in the Blackwing Lair end-game instance of World of Warcraft came to a screeching halt a couple months ago when our alliance of two mid-sized misfit guilds ran into Vaelastrasz. Vael, for short, is a notoriously difficult and tricky fight, and is notorious for breaking guilds that can't seem to beat him.
Well we've finally taken him down, so it won't be long before we're farming the entire instance for 1337 ep1x!!!11!! like we do with Molten Core, which we run from start to killing Ragnaros in 2.5 hours flat. It's not a moment too soon I guess. Our server, Lightbringer is about halfway to opening the gates of Ahn'Qiraj, so it'll only be a few weeks before that instance is available for us to peruse. Hopefully we'll have gotten at least close to Nefarion by then.
