I know the popular thing to do is blame it all on Tynion, but the downward trend was there even before Tynion. At least when not tying into Batman. And right now its well out of the top 100. Which to be blunt, makes what he's currently doing in it rather irrelevant. Because no one really reading it anymore, other than the die-hards who stuck with it. Whats its doing, or he's doing in it, certainly isn't standing out.
They need to do something, and reverting him to something closer to how he was pre-52 Jason is just an idea. Because reverting Jason closer to the person he was before he died isn't really working anymore.
To me reverting him to something closer to how he was pre-52 doesn't sound like too bad of an idea given that thats the Jason they made an animated movie about, and that the Jason thats presumably gonna be showcased in the new Arkham game. Its the Jason that arguably has the most general appeal.
