I fear that someone high up at DC is why we're in this state in the first place.
Percy was brought on Nightwing with a long-term plan. He's not a big name but he brought consistent, respectable numbers to Arrow (I think?) and it seemed like DC was just gonna let him do his thing and basically ignore Dick. Then King had an idea for Batman that involved injuring Nightwing. And Percy's plans got thrown out the window.
I dont know how DC structures its editorial groups or how much those editors have to answer to their bosses for the day-to-day stuff. But whoever approves those things approved the King story and completely derailed the company's plan for Percy-Nightwing. The fact that it threw a title completely out of whack and ruined the creator's plans says to me that this wasn't a run of the mill decision the editors didn't have to get approval for.
What we need is for one of DC's overseers at WB to take notice. As someone said, this is so small-time for those guys they'd need a microscope to notice it, and wouldn't give a damn about the loss of revenue at all. But maybe they'd care about the kind of treatment one of their IP's (one of their more well known ones, if not one of their biggest) is getting. The comics dont matter, but Nightwing has potential in broader markets, and those do matter. That WB manager might not like seeing one of the company's products getting sh*t on, since it damages the brand and that brand could find its way onto the new (unproven) streaming service or even a movie (if that actually happens, which I have many doubts about).
