You know I really like how primals are going back to the story. One of the weakest parts of the 2.x story was how primals showed up for a fight before being totally forgotten. Now we have the original 3 returning in one patch. Maybe 4.0 will deal with the old primals again instead of completely new ones. Just with different versions of them. Hell, maybe even Lunar versions. Elidibus lives on the moon after all.
