Demonic Sunder?

I have noticed there are some enemies (Vilenta when she powers herself up, Depraved Enforcers in Ravaged Square and Control Blocks in Act X, and Bolt Brownfur Earth Churner, one of the bosses in the Courthouse map), who use a variant of Sunder currently unvailable for the players.

Since most of the skills used by Kitava's servants are available in the microtransaction under the "Demonic" category, I would like to see this version of Sunder to be added to the list of Demonic cosmetics.
