#4 None of them can afford a loss at this time
One of the biggest issues with this feud is that neither Strowman nor The Fiend can afford to take a loss at this time. On one hand, Braun Strowman has just got his hands (no pun intended) on the Universal Championship with a massive victory over Goldberg at WrestleMania 36.
And on the other, Bray Wyatt has also come off a huge victory against John Cena in the Firefly Fun House match at the Show of Shows.
The Fiend suffered his first loss at the hands of Goldberg at WWE Super ShowDown and another defeat here would massively affect the character's credibility. The Eater of the Worlds was mocked by the WWE Universe as "Eater of the pins" during his initial run as he failed to come out victorious in major feuds and WWE should be careful about The Fiend not suffering the same fate.
Now that the Monster Among Men has finally captured the Universal title at WrestleMania, he deserves a proper and long run with the title. Having him lose on his first title defense would derail all his momentum.
So the question is, who will win and who will suffer? There's no way both of them are coming out of this feud unaffected.
