M spacegoat also got none of the neon DK hair colors (meaning, no black, no neon green, no neon purple or magenta, and no neon violet)....and they got chicken legs because Blizzard decided they had to skip leg day at the gym, making you look ridiculous in plate armor that doesn't have a kilt/skirt component.
Male draenei also got screwed with their face tentacles, which weren't even updated with model updates as their tentacles are still stiff and low res, and their tentacle rings are also low rez unlike dwarves who got 3D rings on their beard braids.
