These are datamined changes and there could be other changes that cannot be datamined.
Mythic Belo'ren Nerfs
In the latest hotfixes, Ashen Benediction has been nerfed to make it easier to heal the encounter in subsequent phases.
Ashen Benediction now reduces healing done by 5% (was 10%) per phase.
Egg health reduced to 187M (was 208M)
Tank Frontals per combo reduced:
Phase 1 Combo: Does a single Light/Void Edict.
Phase 2 Combo: Does a single Light/Void Edict, then Voidlight Edict
This means that the initial phase will be normal healing, the subsequent phase will be -5% healing (was -10% healing), and the final phase will be -10% healing (was -20% healing). This makes it much easier to 3 egg the encounter, and the third phase will now be as difficult as the second phase healing-wise. However, the egg health change will likely make it so that no guild wants to 3 phase it at all.
These changes are likely related to the Augmentation Evoker tech that was used on Mythic Belo'ren in the Race to World First, as it was recently fixed. This tech massively buffed certain specs in the intermission and made it easier to two phase the encounter.
Ebon Might's radius for applying to allies increased to 500 yds (was 100 yds).
Many guilds killed the boss on Tuesday night and the hotfix wasn't applied until Wednesday night for some odd reason, making it quite unfair for those who hadn't killed it yet. Now with the nerf being after prime time EU, some EU guilds are very sad that they would've killed the boss today but haven't.
About an hour ago, we deployed the following additional adjustments to the Belo’ren encounter via hotfix.
Raids
March on Quel’danas
Belo’ren, Child of Al’ar
Belo’ren’s Stage Two health has been reduced by 10% on Mythic difficulty.
Ashen Benediction has been reduced to 5% per stack on all difficulties (from 10%).
Reduced the frequency of Guardian’s Edict casts over the course of the encounter on all difficulties.
This will appear in our next hotfixes update.
