Description

When reaching Phase 2 on Mythic Sylvanas as soon as the adds spawn the game starts lagging for a few seconds until all adds have spawned. It's not low fps lags but actual lag spikes. This happens on both add phases in that phase. The issue only started occuring since version 3.7.8, I rolled back to 3.7.7 and the lags were gone. After updating back to 3.7.8 mid raid the lags were back right away.

As the issue is occuring for multiple people it's propably related to functionality common WeakAuras used for the fight are using.

As we are progressing that fight I couldn't disable all other addons but I have seen the issue being mentioned on reddit aswell which pointed out it's related to the WeakAuras 3.7.8 update. Other people in my guild have the same issue which was resolved by rolling back to 3.7.7.

What are these? But we think we have a fix in alpha, can you test with that?

I'm pretty sure this is fixed for the next release.

These are the Auras we're using for the fight:
Sanctum of Domination bars for all bosses
Sanctum of Domination icons for all bosses
Chains of Domination assignment
Arrow wait helper

I will test the alpha version in our next raid on Sunday.
