#4. Ambrose vs Rollins at WrestleMania

Rumor had it that, after the original Shield reunion last year, the plan was for Dean Ambrose to turn heel to get back at Seth Rollins for turning on him years back, culminating in this storied rivalry finally getting a proper WrestleMania showcase. Ambrose went down to injury before the Shield reunion realized its potential. That not only took the Lunatic Fringe out of action but sent Rollins into different storyline directions, first with Jason Jordan, then into the Intercontinental Championship picture.
We were probably all better served with a slower burn to this angle. With another year removed, Ambrose vs Rollins feels like it could be a reasonably fresh match-up again, especially with the two reversing face and heel roles.
