ALEX_IV started following Prime Vault July 24: Nyx and Rhino are Primed to return!
Serious question: Why is Nova Prime not being unvaulted? She was retired from the reward tables on November 22, 2016. That will be two years next November. She has been vaulted the longest so far. Meanwhile, if I am not mistaken, Rhino Prime has been unvaulted twice already in the same period. Why?
