#3 To put the title back on Bray Wyatt

If you go back to February, the one thing you would likely change is the decision made to have Goldberg beat 'The Fiend' Bray Wyatt clean in 5 minutes and win the Universal Championship.
With Reigns pulling out of the match, it seemed even worse in hindsight and many would agree when we say that Wyatt should never have lost his title in the first place. Perhaps WWE realized this, albeit a bit late, and decided to start a feud that puts 'The Fiend' right back into the mix for the Universal Championship.

This would also mean dropping the title to him, as sad as it might be. While Strowman is an important figure, WWE will most likely go with 'The Fiend' over him, but we can also see a situation where they have a match with an inconclusive finish leading to an extension of their feud.
However, it's not hard to see a scenario where WWE pulls the rug from underneath Strowman. After all, he was never supposed to be the Universal Champion by this point.
