There's still some good scraps of lore, though it's often overshadowed or dumbed down. Deathwing is a prime example, he had a lot of potential to follow his previous path of infiltrating influential organisations and pulling political strings from within them. Instead, he simply returned as a giant dragon who was indirectly shown to be incompetent whilst burning random things.
