No reason to mess with perfection 
Should I get a tan from the sunwell?

I mean, you’re right, but Dwarves are the beard race from every fantasy setting. You’d figure the first thing they would get would be new beard models.
I will be keeping this toon the same aside from using the longer tail.
None that can’t look even better, just saying!
Vulpera only got new eye colours
And im totally going to use them
Heterochromia all the way
You mechagnomes are nightmarish.
Well for my main rogue (this guy), my other rogue and my main mage, and horde main, nothing is gonna change much, other then a few odd options here and there, like giving myself eyebrows.
For others, 100%. 
I wish I could swap goblin arms onto my tauren body. Now that would be sweet.
There are some characters that I won’t change.
Some that will get minor tweaks like eye color changes
and other that will get a complete redo.
Like this one for example, I just want to add the new warpaint for her. My shaman will probably change her earrings and my warlock will go full out with warpaint, skin colors and more.
Separate nose/ear options will be cool, but I’m still hoping for gilgoblin options in a patch or something!
I’m not entirely impressed with the new options for trolls. I might change the eye color from the default. But the war paint that I was excited for is pretty underwhelming. The face paint options for female trolls aren’t great, and while I do like one of the body paint options it’s not really something I can show off with most gear.
However I am planning on making a troll death knight and I do plan to use several of the new options for him: body paint, earrings, and tusk rings.
they did separate beard and mustache so you can make some new combinations of the two
i dont wanna be a leaf man
So many of my “white” characters will finally have brown skin.
Even my Undead characters, every single one that can be darker, will be darker.
I think I’m good as is.
Planning on taking a look at the tail jewelry for sure.
I’ll have to see what a longer tail will look like.
Beyond that, probably not on this character.
Some of my OTHER characters though… My Worgen is getting a whole new look. That could take me a few hours to get it just right 
None of what I actually wanted is really being added.
I won’t get solid black worgen fur, which I’ve wanted since Cata.
I won’t get stubble facial hair for my human form.
I won’t get new, nice, spiky hair for my human form.
I won’t get differently-colored eyes for my draenei.
I won’t get big horns like the lightforged (and female draenei now) on my male draenei.
I won’t get tail options on my worgen.
I won’t get the option to tank and DPS in worgen form with my claws as a worgen druid.
I won’t get scars or tattoos for literally any of the races I play as, like humans, worgen, kul’tirans, or draenei.
I won’t get upright posture on my male worgen.
I won’t get necklace or piercing options on any of the races I play as (males on the Alliance).
All I get is nice brown hair for humans. I guess I got that, at least.
I don’t get much, and yes, I am salty about it, because I don’t play as an orc.
I’m still waiting on my Draenei Cutie Mark.
THERE’S STILL TIME BLIZZ!
I have to admit that I am tempted to try the new hair colors but I’ve been rocking pink hair for 15 years.
Now the rest of my gnomes…
