Yeah it’s bugged. Like most reports, Blizzard fundamentally misunderstood what we were reporting and thought we were referring to Princess.
We were referring to every mob in the game, because every one has this mechanic.
Basically their thought process was “they mentioned Princess, and she has a flurry ability. Therefore the 10,000 other mobs with the same issue are working fine.”
Essentially the most half-assed troubleshooting imaginable.
