#2 Making The Fiend wrestle too frequently
Bray Wyatt is undoubtedly a great wrestler. However, instead of the in-ring work, the character work done by the Deleter of the Worlds has always been more appreciated. He has been cutting excellent promos, and his sneak attacks have added a sense of danger and edge to his dark character.
By competing regularly, The Fiend will lose his novelty fast. So the WWE should make him wrestle only when it's must, and let him continue with his excellent character work. It may be a better option for him to fight on the PPVs, than doing it every week. This will give him a good chance to show his much-acclaimed charismatic side, keeping him relevant for long.
