I also asked Hickman about the revelation in Namor's last ongoing that _all_ the magic of Atlantis flowed through him, but apparently, that is also irrelevant. Despite the fact, when talking of kingship, it clearly has a role in Atlantean society. He talks about Black Bolt being a destined king, but that's a recent Hickman creation, while Namor's been the subject of prophecy and literally blessed by his god numerous of times, since the Silver Age, as well as tapped as a guardian of sorts against ancient evils such interdimensional threats as Set and Suma-Ket. Plus there's the numerous times in the Defenders where Namor is tapped as an elemental symbol, and his role on the Defenders fated.
Hickman seems to forget that Namor also thought the Illuminati wasn't a good idea, but unlike Panther, he took a seat at the table, because there was NO way he was going to let these other guys make world decisions without having a say or knowing about it. I just don't agree that Namor thinks he's _the most_ important guy in the room -- that's a cardboard assessment of Namor.
Namor can't help but get some characterization, because he's such a strongly delineated character. But he needs his own story, that advances the character. Otherwise, more and more people, and writers, will believe this claptrap that Namor is best as a supporting character. And that's the vibe that I'm picking up. He's only there to prop up Panther and Reed and be a smart a$$.
I hope I'm wrong, but so far, I haven't heard a single thing that is focused on Namor.
