Ion Hazzikostas, Lead Encounter Designer, and community manager Josh "Lore" Allen hosted this year's live raid where Midwinter (US Alliance) and Method (EU Horde) competed in the Siege of Orgrimmar on 25-player heroic mode. All of the raid trash was removed, and the bosses they had to fight were Sha of Pride, Kor'kron Dark Shaman, Malkorok, Siegecrafter Blackfuse, and Garrosh Hellscream.
The race started out with Midwinter killing Sha of Pride a few seconds before Method, but things took a turn for the worse on the Kor'kron Dark Shaman where Midwinter experienced 4 wipes (one of them at only 3%). Eventually, Midwinter breezed through Malkorok and Siegecrafter Blackfuse with little difficulty, but their wipes gave Method the opportunity to kill the next two bosses and get several attempts in on Garrosh before killing him on attempt 3 to win the race.
Congratulations to Method for the win!
