Sorry if I gave the impression that I was dissing Synch or something similar. I honestly wasn't. I may not have grew up on the character (didn't get into comics until a point past that era, and what I've read in back-issues of that era can be sporadic), but I have garnered my own share of obscure heroes I love and want to see more of (which is why I loved seeing Kasper Cole, for example; there are many more where he comes from that I haven't see in a while but I feel really should, like almost every non-Kamala NuHuman).
I mostly said what I did as a peace-keeping thing. The heroes (and villains and etc.) we know to have potential and could use the limelight isn't always gonna be the one to get it (regardless of how frustrating it can get when they don't). Basically, I'm just saying to try not to get mad at Storm being the mutant face for BP as opposed to Synch, as I do feel it makes sense for Storm to be "mutant liaison to Wakanda", and I don't think there's a conspiracy not to use Synch specifically (could be, to be fair I suppose, though Storm wouldn't factor regardless even in the worst case, I'd say). From what I know of the character, I do believe he'd be worthy being in BP's world, albeit not in exclusion of Storm. And who knows? Maybe he'll be brought out of limbo for such a role.
This kinda goes away from my point, and into your disdain for Coates Black Panther stuff. I just wanted to respond to say that I completely disagree with your take on The Crew. I absolutely loved it and feel it's among Marvel's tragically underrated gems. Coates and Harvey really brought it to the fore with that book (which ended too soon), and Eden's focus issue was its own cool and my favorite part of the book tied with Misty and Ororo's togetherness. That's pretty much it.
Well, that, and it would be cool to have Miles interact with Black Panther more, yeah.
Presuming that's the case. Granted here are stories of such, like how the West Cost Avenger's writer apparently wanted to use Julian Keller/Hellion but was denied doing so and so went with Quentin instead. Still, just as likely, Synch's obscurity may have meant the character may have never came up in the story pitchers' minds, period. (Generally, this isn't something that's talked about candidly.)
An aside, but wanted to say that I don't think the quote was a mistake so much as it was simply adhering to the conventions of the fairy tale story being told. It would have become a rather different movie altogether otherwise.
