#1 Dean Ambrose

Bet you didn't see this coming!
While there are a lot of other people that can and probably will benefit from The Shield breaking up again, none of them stand to gain as much as Deam Ambrose does. In fact, between finally getting the main event heel turn he deserves, and most likely getting a title match in the process, Ambrose has the chance to cement his path as a top star.

Sure, it will probably end in Roman Reigns overcoming Ambrose and keeping the title for a while longer, but that doesn't change the fact that his heel turn could lead to bigger things in the future. WWE could even trade him over to Smackdown Live after The Shield split up and have him be the top heel there against guys like Styles and Bryan.
With that being said, Ambrose's eventual heel turn is going to be a big moment in WWE history and it's going to lead to bigger and better things. Not only that, it will finally give him a chance to break out on his own again and give his character the refresh it needed to be great again.
