nightborne got bunch of new customization back in end of SL, i cant see why dhs never got anything done since 2016, perma meta form (visually) meta form skyriding like dracthyr, different hooves/hornes spikes around arms
hair/tatoo/skin colors
red flamey eyes +++ and bunch of everything else
it would be a huge miss not to add more stuff for them for legion remix, it would sell the gamemode 1000x more
oh and a healer spec
