More and more the dragonflights of Azeroth are being tied to the lifeblood of the planet itself. Would it make sense that the humanoid forms dragons can take are limited to races that are native to Azeroth?
The only forms I am aware of ever being used are elves, humans, tauren and gnomes. But I could see trolls, dwarves, pandaren and goblins being possible as well.
If true, this theory would mean orcs and draenei would not be forms dragons would change into. Even undead and worgen would be off limits.
Do you like this, or do you believe that dragons can change to whatever they want?
