Thoughts on this... WotLK - Algalon is prison warden / curse of flesh. Cata - old gods planned deathwing's "breaking" of the world. Mop - shows old ones influence creeping back into the world. WoD - filler for movie. 7.0 - We are the by product of a well laid out plan to release the old gods.
Doubtful since most of the we are titan creations, but not impossible.
