It's been awhile since we've had an update for all races. Humans having gotten the largest in regards to istan.
I know it's not entirely important, but something new for sylvari, charr, norn and asura would be great.
Such as: new ears, body types, markings, faces and hairstyles for Asura
New body types, tattoos, faces and hairstyles for Norn
New fur patterns, hair & Faces for Charr
Combine sylvari male and female hairstyles and create 1 new unique one for each. New faces and body types.
Long hair for asuran, sylvari and humans. More european styled hair for humans. Long braids, curls and better mohawks. Better beards please.
Curly hair for Norn, more cultural styled hairstyles/ nordic. Runic tattoos.
Each major update I look for something cosmetic that isn't recycled. Making my character look unique is about 50% of why I enjoy GW2. The other 50% is everything else (except pvp :c) No, the customization options aren't as great as other mmos but it can be. It can also be unique.
Hopefully, future updates will bring us joy as far as character customization goes.
