There’s no denying the intro was human heavy. I wish they’d allowed us to cross paths with Tyrande in the Maw, but then we’d probably have been following her around as she one-shots everything.
The nice thing is, once you’re past the intro, Human presence dries up. The only Azerothian race I remember from Bastion questing was a Highmountain Tauren at the Temple of Purity. In Maldraxxus, Mograine shows up at the very end, and prior to that it’s mostly Draka, and some of Vashj.
