Shamans use Ghost wolf often, but our form appearances are painfully outdated. The Spirit Raptor model is from Classic Era, and the Vulpine form fits a select aesthetic.
There are DOZENS of wolf models in the game that could be repurposed for Shaman customization with little need for redesign or updates.
The current ghost wolf model is from WoD. The raptor isn’t the classic raptor, I can’t remember when they updated all the classic beast models but it may also have been in WoD or maybe Legion.
The vulpine and lupine just look weird.
They really need to add at least one ghost animal form per race and let us choose from the barbershop same as Druid forms.
