#3. Dean Ambrose

Any hopes that fans had about Dean Ambrose leaving WWE being a work are essentially gone at this point. There was a lot of hope that Ambrose has renewed his contract with WWE, but from the way things are going, there's no plan for him at WrestleMania whatsoever.
While we understand that WWE may not want to book someone that everyone know is leaving, it's a shame because it's an injustice to all that Ambrose has given to the company. He was the iron man of the company, going years without falling sick, years without injury and years on top of the card.
He's still a main eventer in the eyes of fans, and he deserves a good farewell before he leaves WWE. It would be an emotional moment, but the fact that he has nothing going for him certainly doesn't give him a good look.
Either way, if someone doesn't want to stay, they can't be forced.
