#4. Moving on from John Cena
Can you believe WWE finally moved on from John Cena?
While some in The WWE Universe might look back at Cena's stranglehold on the company as good times, it wasn't as well received when it was actually happening. Of course Cena's reign as "The Guy" was justified due to the connection he had with younger fans and his marketability, but it was still a rough ride for fans that preferred edgier content.
Fortunately for those looking for that type of content, WWE finally started to move on from John Cena in 2015, which was also the time that he won his last major championship. With that being said, fans were then introduced to new top guys like Seth Rollins, Daniel Bryan and Roman Reigns, who all took the ball and ran with it.
In all honesty, this wouldn't have been possible five years ago. Not only is that due to the changing demographic that brought about a more adult audience to WWE, but also from just how long Cena had been on top for. It was a changing of the guard that was long over due and five years ago, it just wouldn't have been possible without severe financial repercussions.
