#2 Dean Ambrose

WWE likes to attack the WWE Universe where it emotionally hurts. One such attack was the decision to turn Dean Ambrose heel on an emotional night. Seth Rollins and Dean went against Drew McIntyre and Dolph Ziggler on a quest to win back the RAW tag team championship, as a tribute to Roman Reigns.
Moments after winning the title, Dean Ambrose snapped and attacked his Shield brother. Dean's character has been portrayed as a sadistic man who just wants Seth Rollins to get hurt.
Look who just shut down all of Tony Khan's critics! More HERE.
WWE had been building up Ambrose's heel turn for a long time now, and the impact it created was parallel to none, and couldn't have happened in the presence of The Big Dog.
Dean's character had gotten stale in the past, and he was in dire need of a character change. Hope this brings lots of championships along with it.
