Telash Greywing's Icy Devastator tuning broke

In the Azure Vault dungeon, the Icy Devastator mechanic is doing a lot less damage than it used to. The target it supposed to run away from teammates and healer focus heals them, but recently the damage has been a joke, as if it wasn’t scaled for Season 4 perhaps.

It does 117k dps on Mythic for 3 seconds; less than half the target’s HP. There is zero urgency to heal the target, making the fight super boring.
Compare to:

  • Frozen Ground - 254k dps
  • Absolute Zero (while in shield) - 440k on the whole team
  • Sentinel Talondras’s Earthen Shards - 234k + 137k every 2 sec for 10 sec
