1) Ion literally said you can now play a Wildhammer Dwarf when he unveiled the customization options at Blizzcon last year. This has been followed up by Steve Danuser acknowledging that even though they can't put in story explanations for every single additional race customization (Wildhammer used as an example) due to limited resources, it doesn't mean your Wildhammer Dwarf isn't a Wildhammer Dwarf.
2) Ely Cannon, Blizzard Art Director, literally answers the question of why Void Elves and Blood Elves were given 'blue eyes' by citing that a race -> High Elves, hadn't been represented on player characters.

There ya go dude, supported at 3 different occasions by, at least, 3 different top Blizzard employees on what these new character customizations represent and mean for the players. High Elves included.
You should be overjoyed since you've been claiming you 'saw the light' about getting High Elves.
I'll say it once again, take it up with Blizzard if you're finding something confusing as your statements are getting into the territory of what only Blizzard could answer for you.
This is what they've said about what they've given us, you can either accept it or bombard Blizzard with questions about it, up to you!

It's pretty fitting too because that Witcher hairstyle is named "Wizard" in the selector lol. But yeah the new human customizations have definitely given me more appreciation for my Paladin for the time being, he's going to have that same hairstyle too!
