There seems to be a few camps.
Some feel Blood Elves have effectively gotten things that don’t really represent a major difference for them, such as jewelry, eye color and skintones. Whereas getting things like tattoos for farstriders, or arcane ones for mages, would make a more impactful type fo customization. Meanwhile the Void Elves have effectively gotten a subgroup with High Elf modifications. Many of us in this camp want Dark Rangers or San’layn to fill the second subgroup gap.
Another group doesn’t see the big deal with the skintones and just sees it as the same thing everyone else is getting, which is technically true. New skintones, eye colors, and such are all fairly normal to other AR’s at this time. Usually these folk want to get more things to better fit what they’re looking for or to finish the job of adding choice. Like the Hair colors and styles being shared. Many of these folk seem to be pretty cool with tattoos and such as well.
Then there is a third group that just wants them to be turned into High Elves. They’re relatively few in number I think, and generally want outlandish things like to change the name and “erase” void elves.
And then a fourth group wishes Blizz wouldn’t share anything else further as they feel that the aesthetic and story of a core Horde race is in jeopardy. Which I think is a valid concern myself. One we wont have an answer for for awhile.
Shades of grey between of course and this isn’t meant to put anyone down. >.> Keep in mind I’m biased and in the first group so take this with a grain of salt from me.
