Delay in Castle Nathria - Mythic Sire

Our guild experienced the following issues in Castle Nathria (Mythic Sire):

On first frontal soak (3x triple soak, 1x double soak -> quite a lot of adds spawning)

  • Adds are spawning delayed (and NOT at the same time)
  • All raiders are experiencing >1-2s of input “delay”. This means adds have to tick down to PRE-applied AOE effects.
  • Night hunters are spawning in time, but are “going off” very delayed (often while in the air due to Blood Price ability")

Yesterday we experienced this first hand, have multiple pov’s of this as well.

On wednesday everything went correct (also have multiple pov’s of this). 20 people experiencing the same issues, different ISP’s, different countires and high-end pc’s.

We tried:

  • Resetting instance
  • Resetting instance with different lead
  • Spawn less adds on first frontal (felt better for a while, but got back to a horrible situation where adds are up for +10s due to no abilities going off + night hunters being delayed)

As a guild progressing last boss, this is fully hindering us from progressing anything. It’s a diceroll whether or not we live through the adds dying, simply because we have to wait for pre-applied AOE to kill this.

Is there any other measurements we can take to try and dodge this “instance-lagg / instance-delay?”. After aprrox. 5s after first soak, no more input delay is experienced.
