Now you're grasping at the straws, putting aside all the character development the Outlaws have received through the whole series the most obvious change is that they're a team now, back on issue 1, they were colleagues at best.
And while Kory has gotten the spotlight on two arcs, Jason still has the prominence on the title. It just (how I pointed out before) isn't as obvious thanks to the awful management the book suffered for nearly a year. Seriously, Tynion was an AWFUL choice.
