The guild Mediocrity from Blackrock (US) is the second guild in the world to complete the Earth, Wind & Fire achievement. While Vanquish was the first guild to accomplish this special kind of kill, Mediocrity gives us all the gift of a video so that we can share in their achievement.
You can see how the team split up the tanking duties, keeping one group on Emalon while the other was stacked up on Archavon and Koralon. This is no small feat, and a clear success of coordination and skill. Congratulations!
