I understand what you're saying I've thought about it, and just personally I still like the idea of us summoning the gods more so than us turning into a beast form sort of attuned with the elemental gods. I think it would be cool if instead of turning into gods or versions of them we turn into some sort of elevated buff with visible differentiation while in our advanced jobs. If you're a paladin and damage is being done to you at a frequent rate it fills this gauge and then you receive a visible aura and red or white lines which appear like veins through out your body, and a beserker esque tank mode ensues. So in short I like your base idea of ascendance and transformation, I'm not just not completely behind the idea of us turning into the gods, which to be fair you left it open what we could turn into by saying "what the devs decide on" so i'm not really flaming on it or anything.
