#3 Bring back the original Bray Wyatt
Bray Wyatt stated in his very first episode of The Firefly Fun House that he used to be a very bad man. Whether that was WWE's way of mentioning his real-life issues at the time or just a nod to the inferiority of the former Wyatt, it is still something that needs to be followed up on.
In fact, between WWE already making clear distinctions between The Fiend and the Fun House version of Bray Wyatt, it makes perfect sense to keep rotating characters. At least that way, WWE has an almost endless array of booking options going forward and it also allows them to continue to add to The Fiend's polarizing behavior.

In all honesty, WWE needs to keep the intrigue of Wyatt going as much as possible and going back to his days as a dark woods cult leader would be a great way to do that. Maybe it will even help explain to fans what ultimately brought Wyatt to become the man he is now and add to the spectacle that is The Fiend.
