My post was referencing Marvel pushing the Inhumans over the X-Men in the comics. From the Terrigen Mists sterilizing all mutants on Earth, to it now being considered lethal to mutants, and even Mr. Sinister saying that Inhuman genes are superior to mutant genes in Extraordinary X-Men. Sinister feels there's no need to save the mutant population. Add in things like Avengers vs X-Men (2012), Cyclops being turned into an almost villain (they've walked some things back) and a murderer, killing off of Deadpool (prior to his film release), also killing off Wolverine and retconning Quicksilver and Scarlet Witch from ever being mutants (as well as no longer being Magneto's children).
It really just seems like the X-Men/Mutants in the Marvel Universe are personae non gratae. In the wake of all this, the Inhumans' star has been rising, with more Inhuman titles and event comics and Agents of SHIELD being turned into an Inhuman centered show. All while treating the Inhumans like they are the X-Men. Subbing out one and filling in another.
