Yep, Worgens got massively shafted, I checked and the only thing they got was... customize human option separately and change eye colour? That's it? This sucks.
Also I'm thoroughly disappointed with Trolls not getting dark green skin colour! How come we can make yellow, blue and purple trolls but not green? I always used the "teal" skin colour that was closest to green but I wanted a normal green.
Some races got a lot of new options: Tauren, Nelfs, Orcs, I'd say Goblins are an overall win too.
Some are definitely underwhelming. For example panda tail has only option "short" and "long" meanwhile all the long tails look the same on the new skin colours, I'd love a choice between "striped", "dark", "white", "dark with white tip" etc. I guess I have to stick to ye olde orange panda because that's the only one that has striped tail. The plain ones look meh.
Also I wonder what's Blizz obsession about adding bald hairstyle to every race including females, and plenty of mohawk and half-shaven hairstyles, but very few long hairstyles. Humans got one, Nelfs got one, but for example Belfs got some lame copypasta from Nozdormu / Lorthemar (for female hairstyle) and Pandas got only short ones, and Draeneis only got ponytails and buns and most of them are just variations of existing hairstyles with half of it (fringe) being copy pasta from another hairstyle.
