Been saying this for years:

1. Abandon the hundreds of monthly floppy books and go to anthology digests like they do in Japan. Stick different titles in the same family in the same book - e.g. for DC it'd be Batman, Nightwing, Red Hood, Robin, and Batgirl stories in one collection, JLA, Teen Titans, and individual member stories in another, et cetera. Limit the stories to one per character - none of these "fifteen different Spider-Man titles per month" trash like they have now. Publish those on newspaper-grade paper in B&W so that they're essentially disposable (speculator leeches that slab their books can get fucked), and drop one per week. On months where there are 5 weeks for publication you do a special anthology book - Weird Tales, Sci-Fi, or something that isn't necessarily in-continuity - or use that to introduce new characters/teams that are worth getting their own one-shot to see how they are received.
2. Decree that all story arcs are to be kept to six issues maximum (or that a chapter of the arc can be segmented into six issues), and that all crossovers will either be kept in-family or limited to the fifth-week publication. No more bullshit event crossovers that require the reader to buy every book published to get the whole story just to artificially drive up sales.
3. Stemming from 2, two months after each six issue arc finishes the story will be published in TPB format, in full color on higher quality paper. This allows the collectors of the story lines to be able to have their shelf-book and get the full 4-color comic experience. Other than that, the impetus needs to be on good storytelling with characters that are fun to read. None of the idpol SJW bullshit mouthpieces that we see now. They need to clean house before they implement any of the changes I'm suggesting.
