#1. Goldberg becoming Universal Champion
When Goldberg ended Kevin Owens' great reign as Universal Champion in 2017, the general consensus was "this shouldn't be happening in 2017". Moreover, Goldberg would face Brock Lesnar and it was clear that the two were far bigger than any of the titles and didn't need it for their match either.
This appeared to be the case this time around as well and while we thought that The Fiend would end up beating Goldberg, he hardly got any offense in and ended up getting squashed within minutes.
He was finished by an awful jackhammer and after the match, he got right back up to stand toe-to-toe with Goldberg, only for the lights to go off and for him to disappear.
Goldberg ended the night celebrating as the Universal Champion and the rumor is that he'll be facing Roman Reigns while Wyatt will face Cena. While both matches are great for WrestleMania, it would have been better for Wyatt to defend the Universal Championship at the show of shows.
This entire main event was a big mistake and the title change was the biggest of the show.
