I’ve been reporting that bug alongside a couple other animations bugs on this thread Shaman Earth Shock animation bug for over half and year now, and I also report it weekly with the in-game bug report feature.
Shaman animations seem to break every other patch and if by the time TWW launches those are not fixed I’ll move from updating that thread every major patch to every week.
We already suffer from underwhelming spell effects and lack of good animations and I will not sit idly until the good ones we do have are fixed.
