More primals than elements?

[Ichi]

If each beastman tribe is able to summon a primal then, Goblins, Dragons (If Bahamut isn't theirs), Tonberries, Qiqirn, Mamool Ja and so on would need their own. Can you imagine a Tonberry primal? It wouldn't seem elemental, it would have to simply be a dark, pyschotic being:

I definitely think each Beast Tribe will be able to summon a primal as we've seen even Good beast tribes (moogles) summon primals. Also the devs have stated that Dragons are beastmen and not 'fiends' which probably implies intelligence to the point of sentience despite their lack of a Broca's area (part of the brain responsible for speech) they could still be highly intelligent.

Furthermore we know there are more primals than the the ones summoned by beastmen... Looks like we have a lot to look forward to... and theyll probably add beastmen... oh man this game is going to be around for a while ><;

As per Yoshida in the live letter...

From a lore-perspective, Good King Moggle Mog XII is not a primal and is introduced as a sort of fairy tale which became real due to the effects of the Seventh Umbral Era. Due to this, we have to have a proper story for his appearance in ARR, and we will be implementing this via a scenario in patch 2.1.
