I hate Talos, mostly because him (and Akatosh) have pretty much dwarfed the other Divines. In Oblivion you rarely hear prayers to, say, Zenithar. They're there, but very rare. The Imperials ought to streamline their pantheon into Talos and Akatosh, because that's all they really care about. It sickens me, especially when the former turned Cyrodiil into a forest and the latter's avatar helped bring about one of the most cliche'd finales to a game, ever.
Oh, favorite Divine? Julianos.
The 9 is still on a rocky foundation, because it's a shameless attempt at combining two pantheons that don't agree. You got the nordish part, which makes out the elves to be idiots and pro-humans, and you got the elvish pantheon which can't see farther than the mer's own nose. Also, they probably dwarf the others in Cyrodiil, because Talos was a colovian/nord/??? and people tend to view the colovian part of him. As such, he's going to be more important in Cyrodiil than other areas. Akathosh also dwarfs everyone from the brainwashing of Alessia's pathetic religion, and the fact that he was put on high pedestal with the amulet of kings. Though I do agree with your general sentiment, the others were pretty background, and I would have liked it more if there was a better attempt at expanding the 9 nine religion and diversified the priests, temples, and worshipers.
