I honestly think the frustration with Johns is envy. I stopped caring about his GL books after Blackest Night but I remember pretty much everyone having their own book during the Johns era and for a while after his era.
I find Jordan boring but Johns wasn't obligated to personally write Kyle or John. It was his own choice to use Jordan much like how Snyder is going to use John.
Maybe somebody will use Kyle, there's a good chance that the Morrison rumored book will be about Kyle.
