We are in the process of applying an in-game fix that will restart all of the quests associated with the Midsummer Fire Festival event and allow players to complete them once again. If you are in the process of completing an achievement such as Extinguishing Kalimdor, this fix will reset your progress and you will need start over. This fix will require realms to be restarted.

The hard mode of the Mimiron encounter has received the following changes: the damage of the flames has been reduced, the damage/health gained from the Emergency Buff has been slightly reduced, the range of the Emergency Fire Bot's Deafening Siren ability has been reduced in heroic difficulty and this ability is no longer cast in normal difficulty, the damage of Heat Wave in phase 2 has been reduced, and the damage from Plasma Blast in phase 1 has been reduced.

Then July is beginning, what did it change? Listed below are recent fixes we have applied to the game. Keep in mind that some of these changes may not be active until after the realm has been restarted.
