Since a few guilds had already beaten Heroic mode Elegon before we were able to apply a hotfix to the issue, we chose to hold off on resolving this issue until now to keep the field even during the first week of Heroic progression. In addition to the fix to Discharge, Elegon’s health will also be reduced to offset the loss of Draw Power stacks resulting from the Discharge resolution.
The following fixes will be in place when raids reset this week in each region:
Discharge now properly deals damage in Heroic difficulty.
Elegon’s health has been reduced by approximately 12.5% on Heroic difficulty.
