#2 There is nothing more left to do in WWE
As specified before, Dolph Ziggler has been in WWE forever.
During his time in the WWE, he has won most of the titles. He has won the World Heavyweight Championship, the United States Championship, the Intercontinental Championship, the Tag Team Championships, the Money in the Bank, ... and even a Slammy Award.
Truth be told, Ziggler has achieved his potential in WWE.
Stop and start booking techniques have now ruined the believability of the strength of his character, which might be one of the reasons that WWE audiences no longer care for him. They want someone new and doesn't care about his potential at the moment.
Dolph Ziggler has achieved as much as he can in the hallowed halls of WWE, and given his career, he may even be a future WWE Hall of Famer.
It is time for him to pursue other avenues.
