Corpsewalker + warcry corpse explode

The specter corpses summoned by Corpsewalk don't seem to explode, when using any warcry in conjunction with, nearby corpses explode when you warcry.

Is this an intended effect because it severely limits my damage.

It was changed in 3.25:

"Corpses spawned by the Desecrate and Corpse Walk skills now have a flat 15% chance to match your spectres (or 100% in Hideout areas), rather than a 15% chance on top of being added to the main pool of corpse varieties that can be picked from. These Spectral Corpses are now unusable for most purposes, and can only be used by Minion Skills such as Raise Spectre or Bone Offering."
