Return of the King
And CIS and PIS haven't played a role in Prime's ownage of people? Not to mention huge rosters of characters fighting a single opponent at once tend to job more than a single one on one encounter taking place. Taking a look at how Prime has dealt with mainstream Superman on his own, it's clearly not a massive curbstomp. Prime's > Kal-El, but based on Kal's overall feats, he's not going to steamroll him.
Without CIS/PIS, people like the Flashes can speed up the rest of the team or speed steal the opponents. Green Lanterns can do just about anything. Wonder Woman can use the lasso to ravage souls. Orin and J'onn can telepathically assault people and coordinate with superior teamwork. Batman has no purpose here, but just about everyone else does.
It's a lot closer than what people think, imo.
