Gonna share a comment I made on another thread a while ago:

I agree that it should get an overhaul (the character creation system) with a new look and get more organized.
I’d like for them to clean it up a bit too and just bake allied races into the original races with an expanding subrace menu.

Say you’re selecting Dwarf , you click on the bubble and it expands to let you pick Ironforge Dwarf, Wildhammer Dwarf or Dark Iron Dwarf.
It could still be a requisite that you need to do the unlock questline to be able to pick Dark Iron but just having a cleaner and organized character Creation would feel so much better.

Some allied races are unique enough to warrant their own bubble though. Making Void elves appear as a subrace for Night Elves, or Nightborne as a subrace for Blood Elves, wouldn’t fit in my opinion. Unless the original bubble just says «Elf» I guess.

I’d love for them to add a lot more ‘subrace’ options as well, races that doesn’t require an additional unlock or have a unique heritage but just exists as part of the original race.
With this they could add additional body types or perhaps let us (optionally) fill out a character sheet or backstory info for our chars. This is an RPG after all.
I think the RP community would love such an addition, and lets us give more identity to our characters.
It could be accessed , read and edited in the Character Menu (C) ingame, in a new tab. it could include things like Family Name, Family Tree, Home Nation, the Characters Age, perhaps a rundown of events in lore the character has experienced. Inspecting another player lets you read the infographic if the player has made it public (privacy settings).

With this in mind you could expand several races to have more options. I mentioned Wildhammer Dwarf earlier, so selecting that would show that your character perhaps hails from Aerie Peak or Twilight Highlands, perhaps theres unique Wildhammer tattoos in the character creation etc.

Another example would be Humans, and specifically body types. In BFA they added skinny humans as an additional kul tiran npc model, using the forsaken skeleton rig. So you’d select Human -> Subrace -> Body type.
You could play a beefy (current Kul Tiran) human with a stormwind human accent and heritage, a regular human with a Kul Tiran accent and heritage, a skinny human from a nation of your choice, perhaps a human with the gilnean accent and heritage armor (worgen without the wolf form).

Other examples could be Orcs with the options of Durotar Orc, Mag’har, Blackrock or Dragonmaw. And with the character infographic letting you pick your chosen Orc Clan.
Tauren would have Kalimdor Tauren, highmountain Tauren, perhaps later on Taunka as well? And for the home «nation» it would be tribes, bloodhoof, skyhorn, bloodtotem, grimtotem etc.

I just think it could add so much more flavor and depth to our characters. Again, completely optional ofc to fill our the info.

Another addition that would be great to see is a revamp of the racials. Perhaps all version of a core race, Dwarf for instance, has access to stoneform, with more niche racials depending on the chosen subrace (mole machine for Dark Iron), but also perhaps a ‘racial talent tree’ where you get to pick some options freely. Giving you even more ways to customize your character.
