Gilnean and Darnassian refugees are now gone from Stormwind.
As you probably remember, Sylvanas burned down Teldrassil causing a massive influx of refugees in Stormwind 5 years ago.
Reddit user yuvalal spotted there are no longer refugees present in Stormwind on the 10.2 PTR, which makes perfect sense now that Night Elves have Amirdrassil. The Forsaken have also withdrawn from Gilneas.
I’ve looked on the 10.1.7 PTR and saw no signs of refugees either, so maybe they have been removed even before Patch 10.2.
There are no longer any refugees or giant trees (Ancient Ones) at Stormwind Docks either on the 10.1.7 PTR.
