Most of the player races are not titan creations or mutations of titan creations. It's mostly just humans, dwarves, gnomes, and orcs. Most everything else is either a natural race like trolls(and their many, many offshoots) or a race birthed from wild gods like pandaren or whatever the hell goblins are.
It is really weird that there are a bunch of dwarf primalists around, but I think all the other primalist races are not titan made.
