Exactly, it’s baffling to me how Blizzard has stripped away so much of the Draenei’s connection with Draenor when realistically there’d be multiple generations of Draenei that would have no connection to Argus at all.
Initially, it seemed that Blizzard did portray the Draenei as having very little connection to Argus, having a more heavy emphasis on the importance of Draenor to their people. To the point wherein quest text they emphasize how most Draenei don’t even know of Argus’ existence per TBC quest text:

From what we understand, over the course of the expansions Blizzard has consistently lowered the amount of years that the Draenei had lived on Draenor. From 5,000 down to 2,000 to 200, and in some sources merely 20 years before the opening of the Dark Portal (this becomes increasingly ridiculous when you take into consideration that they’ve built an entire civilization in that amount of time).
Also really weird considering Draenor is literally named after them.
But going back to the initial point, there’s a sorefully underutilized aesthetic that they could’ve used within this understanding. Their shamanistic connections being one of the many opportunities Blizzard has had to express something wholly unique with the Draenei.
That, and of course the initial theming of being a race of exiles in hiding whilst in diaspora from their fallen civilization on Draenor. Lots of aesthetic potential there when you consider the idea of them piecing together their former holdings, traditions, and lifestyles whilst in that diaspora.
An example of a customization option that could emphasize this, like you said, could be stuff like scars, war paint, shamanistic or ritual tattoos.
I do hope that they actually go for something like this in their heritage armor (if they ever get one), instead of opting for the LF heritage armor but purple…
Something more along the lines of this:

Another oddity among Draenei customization is that there’s barely any customization surrounding jewelry. No earrings, nor piercings, nothing beyond a head circlet and the minor customization we’ve been given surrounding tendril-rings. Very odd considering Draenei are supposed to have a strong connection with jewelry, to the point where they have an actual racial passive in the game to emphasize this connection.
