#1 Anything Other Than Becky Lynch Winning The Raw Women's Title
It's pretty clear what WWE needs to do in the show's main event, which is have Becky Lynch win the Raw Women's Championship, and it doesn't really matter who she pins or submits to win the match, although most would prefer it to be Ronda Rousey.
Look who just shut down all of Tony Khan's critics! More HERE.
Since this is the first time the women have main evented WrestleMania, you want to make sure it's a positive experience for everyone involved, as the fans probably won't want to see another women's main event if they come away from this match with a negative attitude.
The only way to please the fans, and ensure that the first ever all-female WrestleMania main event isn't looked at as a complete disaster is to have Becky Lynch walk out of the event with the Raw Women's Title. You can even make the argument that Charlotte Flair's newly won SmackDown Women's Championship should also be on the line, so that "The Man" can end WWE's biggest show with both brand's main titles.
