Several Darnassian Night Elves have made their way to Amirdrassil in Patch 10.2. All of them have new models — most bearing the scars from the Burning of Teldrassil.
Amirdrassil, the «Crown of Harmony», is a new hope for the Night Elves, and the focus of Patch 10.2. Planted from a seed created from Elune and her sister the Winter Queen's tear, infused with the souls of the Night Elves who died in Teldrassil, the tree is being grown in the Emerald Dream until it's large enough to be replanted in Azeroth.
Amirdrassil will be the new home for the Night Elves, and in 10.2, several Night Elves who survived Teldrassil can be found at the tree already, all with new updated models. Most of them even retain the same jobs they held in Darnassus!
