Well, let's hope that one of the things DC stops doing in their all-universe reboot is ALL THE GODDAMN KILLING. Do I even need to mention Countdown To Final Crisis (which was so horrible that the guy(s) who wrote Final Crisis COMPLETELY IGNORED IT while writing it), which could have just been re-named "Pointless Shit and Killing, the 51-Issue Mini-Series." This is a simple concept, DC Editorial. Write interesting stories about the characters and we will want to read them. We do not want to see people and superheroes getting killed in a pointless fashion where the only point is to be a shock moment in a story, good or bad.
Actually, that's another thing comic companies need to address; their editors playing writer. An editor's job is to correct punctuation and spelling and make sure everything is consistent on an artistic and writing level. Their job does not include "writing the stories and/or dictating how a character arc is supposed to flow." If editors want to be writers, fine, write a story. No problem. Just don't do it where you're messing with a previously-established storyline or character. When editors try to play writer, it ends up never working and being universally hated. Example, remember That Mini-Series I Mentioned In The Last Paragraph Which Shall Never Be Addressed By Name Ever Again, or as I like to call it, TMSIMITLPWSNBABNEA (just rolls right off the tongue, don't it)? Yeah, that was completely editorially mandated the entire way because DC Editor-In-Chief Dan Didido (and I do apologize for any misspelling or calling out the wrong guy) hated the previous weekly mini-series (which was far, far better) 52 for no adequately-explained reason other than the fact he's a damn moron and that TMSIMITLPWSNBABNEA was, and I kid you not, "52 done right" because the editor got to control the story as opposed to the WRITERS. Y'know, THE PEOPLE WHOSE JOB IT IS TO WRITE STORIES.
Sorry if this came off as a rant, and I know Marvel, and I assume Image and Dark Horse, has problems with pointless killing and editorial interference (perfect example, Joe Quesada and One More Day), but it's just so much easier to find in the DC Universe.
