I don't think the shoulders looks good with anything else for NB, but eye of the beholder of course. I like it simple, but as you say I need to take another step in the color department to make it work.
Mhm, you were maybe talking about Void Elves? Yes, the shoulders(or chest rather) is very nice and have some uses outside heritage. If so, I do have several different sets with Void Elves, and it's a lot easier for Velves, for sure. On hunter I got gray hair with mythic t19, on rogue I have used mythic t18 a lot with dark red hair, my warlock has tier5 with red hair, on mage t21 gladiator is very nice.
Best one is my DK. Where I use mythic t21 with the void wings and ebon blade tabard. I am Frost on it so I am very happy with that one.
Did not mean it's so hard to find other sets on Velves, but with the new options it just opens the possibilities immensly. Though on Nightborne I got issues. I found some red set that was decent, but its heritage or nothing for me there. My lack of imagination I guess
