Deleting all of Marvel is extreme and ridiculous. And I do think you overrate how inconsistent Marvel is. EndlessMike, who has read every single Fantastic Four issue and is doing the same to all Avengers issues, and is likely the most knowledgeable debater on Marvel, doesn't think they are as bad as you do.
I don't get why using the author / guidebooks definitions of Omniverse is wrong,specially since marvel profiles here are putting guidebooks over feats.
With my own experienced with DC Comics, I've had a very easy time ranking and analyzing characters by reading the issues and searching for consistent feats. Dc uses almost the same system as Marvel and and a lot of the same writers, and I don't think there's anything magical about Dc Comics that makes it supposedly less inconsistent.
TOAA itself is no more vague than Kami Tenchi, and both are defined as boundless and Omnipotent even to those who transcend all definitions of everything. It even directly stated that, when it said that Thanos having Omni-Reality existence was a fraction of him.
By ignoring all Megaversal and Omniversal feats, we ignore Marvel as a whole. We ignore their own cosmology. If being beyond Multiversal structures was defined as 16-D, we can use that. If the Omniverse has been defined as a High 1-B structures in multiple guidebooks and Comics, we can use that too. No Writer has any obligation to define all the cosmology and concepts in every new storyline, because they have been defined before. And I don't get why we are só easily rejecting High end feats yet low-end feats are being used to downgrade characters.
I understand that Marvel frustrated and tires you, and that you went from a long time fan to practically hating it...but do we really need to be this restrictive, biased and hold such little faith in the writers? Demanding that every single storyline gives the characters consistent High End feats would destroy any franchise, even those maintained by a single Writer. Marvel is very loose in terms of power and canonicity, só shouldn't we reflect it's nature?
I'm starting to consider reading every issue with The Living Tribunal and Eternity in them, and making a Respect Thread to discuss ratings.
