Recent datamining has uncovered a Heart of Azeroth animation on Gilgoblin male and females. It has been discovered that 9 new animations have been added to the Gilgoblin male. There was 281 and its now up to 290. The Gilgoblin female has 290 as well. I am unsure which other animations exactly where added, but there were new animations added upon the Nazjatar release. Mechagnomes have also been found to have a heart of Azeroth animation on them too. Now Nazjatar and Mechagon have only been out a short time so it makes me wonder if later on they are going to be getting cutscene data or other stuff pertaining to them being potential allied races. Both seem to have a lot a huge amount of story relevance in the new areas too and Gilblins/Kelfin I suspect may get a model update 8.2.5 like other race variants have in past player model updates.
