#1 The Shield

The Shield reunited on the Raw after SummerSlam. While the reunion of the group has been great as it abruptly ended last year due to Dean Ambrose's injury and Roman Reigns has been cheered when with the Shield, the Shield should break up before WrestleMania 35. It would be a perfect opportunity for them to face off in a triple threat match at WrestleMania for the Universal Championship. Dean Ambrose should be the one to cause the group to break up. Seth Rollins did it to Dean Ambrose a few years ago and as a result, Dean Ambrose should want to get retribution after more than 4 years. Ambrose could attack Rollins and Reigns can try to stop him. Ambrose will then lay Reigns out with Dirty Deeds. Dean Ambrose can finally be a heel, Roman Reigns can be the no-nonsense face, & Seth Rollins can be the sympathetic figure.
