Progress of EU Firemaw was the first guild in the world to clear all of Mount Hyjal and Black Temple in Burning Crusade Classic. Progress had previously achieved world first Serpentshrine Cavern and Tempest Keep, so they are definitely the guild to look out for Phase 5 of Burning Crusade, when Sunwell Plateau releases.Progess Video of Multiple POV During Black Temple

Top 10 rankings of 14/14 Tier 6 Raid progression

Many guilds chose to fully clear Mount Hyjal right away, while some made the choice to leave directly after killing Rage Winterchill to get a head start on killing Illidan Stormrage. While Turbulence did technically get the world first Illidan kill, they chose not to fully clear Mount Hyjal before heading to Black Temple. That means Progress was only a minute shy of getting the first Illidan Stormrage kill, and they didn't skip Mount Hyjal after Rage Winterchill! The reason guilds weren't able to zone directly into Black Temple at release is because the attunement to Black Temple requires a kill on Rage Winterchill, to collect Time-Phased Phylactery. Rage Winterchill is the first boss in Mount Hyjal, so some guilds had to face the difficult choice of leaving early if they wanted to achieve a world first kill on Illidan Stormrage.
