How would you feel about them actually allowing hundreds of different options like Skin tone, Tattoos, Age, Eye color, Hair styles, Genders, Non-Human races, ect?
Could get even more options if there were separate factions like Angelic and Demonic leaning choices.
More customisation options are always fun, but it’s all for naught if the gameplay is lacking, so I hope that’s where the primary focus is. Otherwise, hell yeah, bring it on! I reckon a solid 30% of my total playtime in any game that allows you to customise your character is just me getting them looking exactly the way I like 
This has already been confirmed. Character customization choices start with the class, then gender. From there, you can choose skin tone, eye color, hair style and color, facial hair style, tattoos, jewelry, and other classs specific visual traits. Basically everything except voice, height/weight/size, and what handed they are.
Also, on Sanctuary there is only one race and that is Nephalem. There are no other humanoid races we would play unless they allow us to be a Demon. But I suspect if that were to happen it would be it’s own class.
If it comes with a one time purchase sure (i.e. base game or full DLC package). The prices they put on individual microtrans often I find too expensive.
I think they can go one of three routes.
remove any character appearance (not grear, only the actual person) customization and go with the standard looks as usual.
Offer a few presets, just so people have some say in what their character generally looks like (Like what we saw in the demo).
Offer a wide range of realistic modifiers, allowing for control within reason.
I think 2 is a pretty good option, though I am happy with 1 and 3 as well. I would not be happy with them allowing people to make their characters ridiculous looking, such as a 10 foot tall neon pink bararian. That is silly and immersion breaking. It is fun at first, but gets old and doesn’t fit the game.
I think they should make it a bunch of preset pieces that look good. like a handful of skin tones, faces, and accents (tattoos, piercings, etc. Whatever the class is known for). They don’t need to go all out and spend lots of time allowing you to use tons of sliders. Their time is better spent elsewhere.
A handful of options like hair color/hair style (if you go without helmet) should be enough. Gear covers most anyway so a bazillion options are just overkill.
And boob sliders just mess up the armor models. 
Im not that big of a fan since character is far away, I rather have my customization come from cool looking armor and weapons that are unique and hard to find etc.
Don’t really care that much.
As long as they’re correctly designed (I mean, no longnecks in underpants or weird marauder faces), I’d be OK even with zero appearance customization.
I enjoy games with character customization in it, however oddly enough I wouldn’t mind if Diablo 4 actually forgoes that completely. However by the looks of it, we will be having a limited aspect of character customization when creating our characters. I do wonder however if transmogrification would be making a return (talking about the non-mtx version).
On this note, and it is a bit off-topic, PLEASE do not make us turn into super saiyan barbarian (and other chars) where we look over the top ridiculous and lose all the appearance of our character and their gear.
I was really not a fan of the barbarians rage mode skill that transforms him. Looks more like something that belongs in Dragon Ball Z or transformers, not Diablo. While not nearly as absurd as that, I also didn’t love Diablo II’s shapeshifting, since you never see your gear, rather you are always the same exact looking bear/wolf. And on top of it, they were probably the two worst looking things in the entire game. You have the rat-wolf and the miniature six-pack bear very odd posture.
I’d love to have deep customization and so that it would mean something like in DnD. For example, old-aged wizard: permanent -10% movement speed, but +10% spelldamage.
I just hope there will be an option for me to turn off other players’ visuals and just see a basic preset of a Barbarian, Druid, etc.
IE: I don’t want my screen clogged up with wings, transmogs, pets, big elaborate horses, emotes, etc while I’m forced to interact with other plays in a hub or world boss setting. Just show me a basic player skin and that way I can move along without the drop in FPS that will surely occur if every player on the screen has a different set of sparkling and animated MTX skins, wings, weapon effects, etc. POE’s Heist launch was HORRIBLE when it came to performance in the heist hubs because of the MTX lag.
Honestly that could be solved with:
That way players who don’t like transformation skill buffs (like Akarat’s Champion or WoTB) can opt to disable the visual effects of the transformation. Of course transformations that are either linked to other active skills or possessed skills unique to that transformation (like the druids shapeshifting) should probably remain unaffected.
The thing I like the least about customization is that it sometimes denaturalizes the class identity. I believe that fantasy worlds don’t justify everything.
Same way it wouldn’t make sense to me a male Amazon or a white Witch Doctor, I struggle to understand a black Barbarian.
It’s less of an issue for me as long as they explained how it why it happened. For example instead of just bringing out a male amazon; give out an explanatory backround telling about how the Askari people began training both their women and men after they suffered terrible casulties due to the actions of Malthael and his reapers.
Same could be done with a black barbarian or white Witch Doctor. Giving an explanation about how the Children of Bul-kathos became wanderers (which most actually did) and settled down in other lands where there are people of darker skin tone or how adventurers of lighter skin tone were allowed to stay within the lands of the Umbaru could easily explain being able to customize a character’s skin tone (although Witch Doctors haven’t been confirmed in Diablo 4).
They would just need to make sure that none (or most of it) doesn’t clash with existing lore.
I dont really care.
Not going to look much on my characters anyway, and when I do, they will have a ton of items on them.
More options seems fine though. Just shouldnt spend a ton of resources on something fairly insignificant however. We dont need Elders Scrolls and similar character creators imo.
Wouldn’t go that far, to have age matter, but some kind of background choice for each class, that affected its look, could be cool.
I have previously mentioned druids being able to choose their “totem animal”. The large dude from D4 demo might be a druid with a bear affinity. Wolf druids might have a different body type. And of course, these choices would then offer some small gameplay bonuses too.
Sorcs might pick a magic school, barbs an Ancient or clan preference. Etc.
Also this.
There’s very little chance they’ll let you hide cosmetic effects because they want you to see the pretty mtx items that people have bought. It effectively acts as free advertising for more people to buy those items.
Beyond that, giving people some options for basic character appearance wouldn’t really cause any framerate drops unless they do some really weird stuff with it.
You have to give them the correct names:
They already did that part fine IMO, if you look at Blizzcon every class had like 2-3 models and each could’ve had changed tatoos and skin and hair colours
Personally think that’s enough, the facial stuff other than hair and facial hair is mostly “meh” considering you won’t see your character’s face details most of the time… Wouldn’t want to spend like 20 minutes at a character creation screen lol
Oh I know it does. But if and when I decide to throw a few bucks their way, I’ll just look at what’s available and make an informed decision at that time. I’m not so weak willed that seeing something shiny on somebody else will open my wallet any faster.
As a matter of fact, I’d be willing to PAY to get that option I described. 5 bucks to never see a barbarian do a dab or the backpack floss dance? WORTH IT.
