4. Seth Rollins v. Dean Ambrose
When Seth Rollins joined The Authority, it devastated Dean Ambrose the worst. Ambrose would cut a very emotional, angry promo the week after Rollins joined the Authority which set the tone for their feud in the summer of 2014.
The two would feud until Hell in a Cell, where they battled it out inside the Cell. Ambrose proved he was definitely a lunatic with some mind games to infuriate his former friend. The next year, Ambrose would play with Rollins once more when he stole his WWE Championship for a few weeks.
Now this year, the tables have tuned as Ambrose is now the WWE Champion and Rollins is chasing him in their third summer feud. Kudos to them and WWE for keeping this feud fresh over time.
