After an 11 day race, Echo has claimed the world first Mythic Raszageth kill and the world first clear of Mythic Vault of the Incarnates. Congratulations to them!
After 11 long days, Mythic Raszageth has fallen! This boss has received massive buffs before the raid released and then numerous hotfixes (1, 2) after players were working on it, so Blizzard clearly overestimated how much damage players were going to be doing.
