Developer Comments: The addition of Ragnaros to the Nexus has once again unmistakably proven how painful it is to stand in fire. Lava Wave and Molten Core seem to be the leading power-houses of the newly released Raid Boss, so we are targeting the majority of the changes at them. We are also carefully monitoring his interaction with the Battlegrounds and are prepared to make adjustments as needed.

Bug Fixes

  • Ragnaros: Pressing ALT + R will now properly self-cast Sulfuras Smash.
