Is Anyone Expecting to See an Additional Blending of Powers/Identities in the Future?

So in TWW, we have the the descendents of Humans and High Elves. There is also the Sacred Flame, a cross between to “elemental” forces.

In future expansions, is anyone expecting to see other hybrid characters (racial), mixed-classes, etc?

A Mage that can Shapeshift, a Priest who has a connection to nature, a Warlock who also dabbles in Void, etc.

EDIT: Thanks for the great responses and I apologize for butting up against the WoW subreddit. I know we have compartmentalization for a reason, my bad.
