#3 Less talking
Bray Wyatt mesmerized the WWE Universe with his promos when he first came to the main roster, but who would have thought that would eventually work against him? In fact, who would have ever guessed it would become one of the things that hurt his original gimmick the most?
Yes, Wyatt's character talked a good game and was able to entrance fans and other Superstars with his use of symbolism, but that would be weakened over time when he would lose a feud or ultimately fail to do what he set out to do. The way his storylines were handled made it difficult for fans to appreciate his words once they realized they were essentially meaningless.
All that changed, however, with The Fiend gimmick. Wyatt isn't as talkative as he once was and his what he said is pointed, never rambling. That makes the words he does say matter a whole lot more. Furthermore, WWE's new strategy of having Wyatt talk less seems to always leave the fans wanting more and scurrying to the internet to speculate about what his latest promo meant.
Compare that to Wyatt's old character, who seemed to reiterate the same thing in a different way every time he got on the microphone and you start to see how much different and refreshing the new character is.
