#2 A long-term storyline and Braun Strowman's character

One of the best parts about 'The Fiend' Bray Wyatt's character is the impact that he has on other Superstars. As we've seen with Seth Rollins and The Miz, they would turn heel not too long after losing to Wyatt, while Daniel Bryan remained a face.
Braun Strowman has been a popular Superstar for years now, but there's going to come a time when he needs a major character shift or at least progression to stay fresh. Now that he's the Universal Champion, that change needs to come sooner rather than later.

Which Superstar is better to fuel that character progression than 'The Fiend' Bray Wyatt? Either he loses to Wyatt and has a character change, or wins and it adds to his character in a big way. That's one department where Strowman needs to focus on it to avoid getting the 'Seth Rollins treatment' last year.
Perhaps the two could even be in for a long-term storyline - one where Strowman possibly aligns with Wyatt.
