Players have been experiencing severe lag issues inside the new raid, the Sanctum of Domination specifically on the final encounter Sylvanas Windrunner.
Blizzard commented on these issues a few weeks ago, giving explanations as to why it was happening and what they will be doing to improve it.
A hotfix was applied shortly after Blizzard acknowledged these issues, but they also announced that further changes would be made.
Today we see those changes announced, and will go live alongside weekly maintenance this week.
World Of Warcraft Hotfix Targets Sylvanas Performance Issues Inside The Sanctum Of Domination
- Optimized game performance at the initialization of the first two phases of the encounter.
"Thanks to community reports, we discovered a way to optimize the processes that caused performance drops at the beginning of the fight and at the beginning of the second phase of the fight (the bridge scene)." Blizzard say in the patch notes.
- Fixed an issue where Mistweaver Monks could be preferentially targeted by Wailing Arrow in Stage 3.
- Fixed an issue where both Tank-specialized players could be targeted with the same Black Arrow cast.
- Fixed an issue where Dark Sentinels could cast Rage on targets struck by a very recent Black Arrow.
With close to 400 guilds already having defeated Sylvanas Windrunner on Mythic, this change will help many of the next guilds progress the fight to deal with fewer lag issues, which can be demoralizing for many guilds.
Now Blizzard has identified what the issues were, players hope to see fewer lag issues on the next raid's final encounter as it has been a trend lately for final bosses.
