Blizzard has provided an update on the Nerub-ar Palace latency issues that have been plaguing Patch 11.0.5. As of today, desyncs and disconnects should be reduced with more fixes on the way soon.
This work is being done now in preparation for the game’s future needs as it grows. Unfortunately, we experienced side effects that have been seen in certain high-performance parts of the game, such as several encounters in Nerub-ar Palace.
We’ve been working on these issues with urgency, and earlier today, we have deployed hotfixes that we believe will reduce “desyncs” with certain boss abilities, and address sudden disconnects during combat.
We have more fixes on the way, including improvements to client responsiveness during raid encounters.
We’re continuing to stay focused on any game performance issues that remain, or arise following today’s fixes.
