I changed the skin of my main (Void Elf Shadow Priest). This option should have been available since 2017, I don't know why Blizzard took so long. Having fair skin was always part of the Ren'dorei identity, as Alleria Windrunner is the leader of the Ren'dorei and a Void elf who retains her fair skin form.
Now I hope Blizzard focuses on the exact opposite extreme and gives us more corruption options. N'Zoth eyes, more tentacles, maybe astral hair, etc.
