I'd love to see more character customization options in WoW.
For a lot of the hairstyles, beards, piercings, etc, I feel like it wouldn't even be too hard. They've already got a lot of existing models that could just be copy pasted (and maybe resized a bit) from race to race to add a LOT more. For instance, there are plenty of goblin hairsyles that would work very well for orcs and trolls too. Or plenty of troll ones that would work for orcs and goblins. Hell, why not just let ANY race use ANY hairstyle? That would add the most options possible, it would please basically everyone since they're get more choices in general, and even if some people chose to have patchy undead hair wisps on a human, most people wouldn't.
Also, the absence of piercings is unfortunate. Even the races that already have piercings can't do as much as I'd like with them. Goblins have lots of piercing options, but they're all tied in with the nose, ears, and chin. Why can't I choose my chin, nose, ears, and piercings individually? And why can't any race choose to have those same piercing models? I'd love a septum piercing on my orc warrior, and definitely some Vol'Jin style gauges on my troll's ears. The troll's face paint is also tied to their tusks, and tied to specific colors. If we could choose paint style, tusk style, and paint color individually, it would be SO much better.
Tattoos as well. Everyone wants that. Although I did see some tattoo shirt models in Legion, I believe, so maybe we're getting some finally. They'd be a lot more work to create than just copy pasting existing hairstyles and piercings onto every race though. I feel like that's even more to ask.
Sure, some people may like certain races having exclusive looks, but plenty of other games have every hairstyle available to every race, and no one cries about that. Just the fact that WoW has always had such restrictions in character creation is what makes the difference notable.
I feel like some of these additions would be the perfect thing to add whenever Blizzard gets around to letting us play sub-races. I know that's also something a LOT of people have been asking for, and I can't imagine it'd be much different to add new skin/eye colors that already exist in the game files to the character creator. I can't really see this happening until possibly an expansion after Legion, but if we got a big update patch with this stuff DURING Legion, I'd be in heaven.
What do you all think? Feel free to discuss and/or disagree.
