I almost completely agree with your description Arciel but I wouldn't say you're "correcting" any one. Parts of that you are just submitting your own interpretation because there is no current official story related part to tie it together.

Regarding your view of Carbuncle being labeled a trickster because of him misleading Summoners to siphon power for his own cause. Carbuncle was very clear on what he asked of and never tricks you into doing it.

He is very clear from the beginning what his goals are and explains them even more during Waking the Beast. I can see how the Celestial Avatars however, think he's a trickster simply because they find him to be a false god and don't trust him.

Odin and Alexander are grouped together with the other Celestial Avatars because that's what they all are. They aren't asleep but it doesn't put them in a separate category. They each have dominion over 1 of the 8 elements of Vana'diel, awake or asleep.
