My only thought in all of that though, the pet job thing... do you realy feel that Primals can be justified in becoming a leashed pet? Doesnt that annoy you, to think that you're diminishing this grand God like creature into a little pokemon sort of sidekick? If you truly love the grandeur and power of the Primals, in whatever game or fashion they come from (XI excluded in this obviously) then you shouldn't want them to bring the Primals down in such a way.

Instead, encourage them to find a way to make calling on the Elementals themselves (which, you know if you read any of the gridania stuff, or white mage quests...the elementals are Not weak, they destroyed an entire age. I mean, come on really. They literally changed an entire AGE. My burst sucks compared to that. lol) but anyways, encourage SE to make the Elementals themselves more meaningful and badass, think GW2..I think its GW2, where the Elemental spirit gradually becomes bigger and thus more powerful as its level increases, until its finally this massive beast of power.

And allow them to keep the Gods themselves something big and epic and worthy of their name.
