There is also that Genesaur & Magnaron.
Though it is possible they came along with the Mag’har as we’ve seen a few of non-orcs escape Draenor after the scenario.
(And also the lightforged gorehowl in China)
Though I hope the map is just a reused asset, they need to leave Draenor in the past where it belongs.
Though it would be hilarious if they subverted expectations and the Lightbound are brought in and aren’t villains.
