I’ve been asking for racial ghost forms for years and my list is similar but slightly different:
Orc - Dire worg
Mag’har - Current wolf form.
Troll - Current raptor form; remove the glyph.
Zandalari - Ravasaur
Tauren - Tallstrider
HMT - Moose
Goblin - Hyena
Vulpera - Vulpin
Panda - Crane
Dwarf - Ram
DID - Darkhound
Draenei - Talbuk
Kul Tiran - Goat or crab. I kinda lean more towards a crab because the KT are supposed to be in tune with the ocean and all that.
