More primals than elements?

[Ruanark]

Considering the similarities between XIV and XI when it comes to Primals and Avatars here's a list of the Avatars and groups they fall under:

8 Celestial Avatars
Shiva, Ifrit, Leviathan, Ramuh, Titan, Garuda, identical to XIV, but then there are 2 more elements
Odin, Alexander, so far Alexander hasn't been mentioned and Dark/Light aren't elements like they were in XI

5 Terrestial Avatars
Bahamut (Dragon, Nonelemental/Fire idr, The Wyrmking, Conqueror of the Skies), Carbuncle (Fox, Light, The Bringer of Rainbows, The Trickster), Fenrir (Wolf, Dark, The Great Beast, Guardian of the Moon), Diabolos (Bat, Dark, Lord of Dynamis, it's Diabolos and NOT Diablos), Phoenix (Bird, Fire/Light?, Fiery Bird of Rebirth)
So far we have Bahamut, Carbuncle (who is not a Primal... as far as we know) and Fenrir (who may/may not be a Primal), only missing 2 of the Terrestials in XIV

2 Temporal Avatars
Cait Sith (Light elemental?), Atomos (Dark elemental?)
Atomos is a voidsent in 14?

We actually had Astral and Umbral (Light/Dark) elements up until the major battle system change in 1.0 (patch 1.18 if memory serves). Since then they have taken a backseat, but I wouldn't count them out just yet. From playing around with Arcanist in phase 4, it appears they may be tapping into those.

FF has a strong balance between Light and Dark theme(With Astral/Umbral being its representation in this particular incarnation). What if the 12 are the Light aspect with Each primal being a Dark aspect. With each Primal matching up with one of the 12(thus having 12 primals)
