#3 The Fiend should not be competing so often
Remember the reasoning that Paul Heyman gave when asked about the limited appearances of his client, Brock Lesnar? He said that the Beast Incarnate only appears on a few major shows because he's a "special attraction". Well, I'm not supporting any part-time wrestlers here but that statement makes a lot of sense in the world of pro wrestling.
Much like Lesnar, The Fiend is or at least should be treated as a special attraction by the company. Many fans were expecting Wyatt to take a small break after his massive WrestleMania victory over John Cena but he has been pushed into the Universal Title picture immediately.
Of course, WWE has many ways to creatively use Bray and The Fiend in an empty arena show but they should be careful and not overuse the character - this might result in the mystique surrounding the character dissipate.
It might just be me, but the quality of the Firefly Fun House segments have gone down considerably as compared to the initial ones we got just after the debut of this new Bray Wyatt. And, part of it is because WWE airs it almost every week.
WWE needs to maintain the uniqueness of this character and make fans miss it and want to see it.
