Batman: Arkham Knight is a fantastic game. However, after 100% completion, there isn't much incentive to play in the open world. AR challenges are the only replayable activities in the open world. If the Most Wanted side missions were replayable after completion, it would add a lot of replay value in the open world alone. The game Watch Dogs recieved a patch update that gave players the option to reset side missions. After you've completed the game and you're not done being Batman, wouldn't it be great to take down Penguin and Two-Face (plus others) over and over? Batman: Arkham Knight would be even more fun with this option.
