Part of me hopes there is no race and instead we all get to transform into a Dragon as part of the story. We slowly empower up "Dragon doohickey" and unlock more abilities. Different skins can be unlocked for our appearance similar to Legion artifacts. Each patch could have a different flight as the focus. It could unlock a flight form for everyone.
I'd settle for the Tarecgosa legendary mount being a learned thing though so I don't have to keep my staff equipped to make use of it.
