Unholy DK defile visual

Why isn’t anyone addressing the issue with “Defile” covering all swirlies and all other layers?
“Emberon” tornadoes were fixed right away, is it really that hard to make defile look just like the normal death and decay? Unholy is mostly unplayable because of it, and I just depleted a 25 key for a group I joined because of it !
How long is this going to be ignored?! Is it really a great issue beyond Blizzard’s capabilities?
This is disappointing.

This forum is for reporting bugs in Blizzard’s API (Application Programming Interface).
I would imagine you’d get ignored less if you posted in the right place…
