Quality helps only if someone is willing to read the book.
Part of the issue is someone has to read the book from the start versus later on. Which is why many take issue with these quick cancellations be it comics or tv shows.
Because it ignores outside factors.
Take network tv-how many new shows get axed during now to Thanksgiving?
How can a show that is new on say Thursday night survive Baseball playoffs, NFL football, college football, early college basketball, NBA starting up, NHL starting up, ABC's Thursday night and whatever CBS & NBC toss out? Especially if you are Fox or the CW? Let alone cable tv. We won't talk Monday night or Wednesday Night.
You can have the best quality show-how are you going to make it especially if you target the same folks who worship Scandal or Criminal Minds or whatever NBC has now.
Same with comics-
We saw it with Vision. A WAY better book than many we could all name that we have READ. I am sure Ninjak at Valiant is good but because it's VALIANT and not Marvel or DC-it gets ignored like Faith.
So for many books you have to get past issue 3 to warrant issues 7-12. Unless your name is Cyborg or Carol Danvers. Which is why many got mad about BP: The Crew. Preorders on Amazon.com at one point had higher sales than most books already out Heck BP WOW is a top 100 seller for all Superhero trades. While Moon Girl, Miles, Gwen, Hellcat & Squirrel Girl are there as well.
Quality can effect sales but as I keep saying someone has to give the writer a chance. The point Redjack was making.
No one knew who Alan Moore was.
Who was Priest? Just the guy who made Black Panther a seller and the starter of 11 years of solos for him.
Who was Liefied? Some guy who taught himself to draw and took over New Mutants and gave us Deadpool.
NO one knew who Blade was until Wesley Snipes said HELLO.
