The Dark Portal to Outland may have just opened, but many players in one of the world's top World of Warcraft: Burning Crusade Classic raiding guilds have already reached level 70.

According to Wowhead, a five-man group consisting of members of the guild Progress have claimed the title of world-first level 70s in Burning Crusade Classic, with player Hacez hitting the milestone first. Other members of Hacez's group hit 70 shortly after. The total time to hit the game's newly released level cap was about 13 hours.

The group achieved the feat by stockpiling completed quests at level 60 and turning them in as soon as Burning Crusade Classic launched for some quick experience. From there, the group spammed dungeons for hours on end until hitting level 70. Progress is said to already have more than enough level 70s to begin running the game's new 10-man and 25-man raids, putting it well on its way to achieving world first clears of Karazhan, Gruul's Lair, and Magtheridon's Lair.
