Well how many characters listed as being in it have not been used in awhile and need trademark retention?
When in doubt, the search for more money and the need to retain trademarks will always be the reason.
Which is why we must continue to suffer the constant reboots and dreadful stories of Carol as Captain Marvel when reviving Mar-Vell for good opens the door for many interesting stories, imo.
as to the recent Allegedly Superior Spiderman series, I knew it wouldn't last long and Doc Ock being reset is no surprise to me at all, but once again Mephisto is Deus Ex machina
dark deals perhaps and Marvel planning Ock in the next Spider-Man film?
Remember Peter was a given organics because of movies.
