Horde allied races are reskin as well, including vulperas, they are goblin reskin.
There are only 2 allied races that have complete new model and animations: Kultirians and Zandalaris.
I hate see people from alliance complaining about Kultirians, cause makes no sense. Yes they are humans, but is a complete new one, not a reskin, and they have a badass strongman looking in my opinion.
If blizzard added the thin kultirians, maybe people would not complains so much.
