#5 The Shield (Worked)
Even though The Shield debuted as a heel faction, it was quite difficult to hate the trio. The Shield was one of those rare modern era heels who actually backed up their words with action.
Throughout 2013, The Shield feuded with countless Superstars and Teams, both of the past and present. At Extreme Rules 2013, all 3 members won Championships (Ambrose became the US Champion while Rollins and Reigns won the Tag Team Titles). The Hounds of Justice turned face in 2014.
Rollins, Reigns, and Ambrose were already loved by the fans so turning face only increased the frequency and loudness of cheers. The Shield had an incredibly amazing feud with The Authority and Evolution.
Their face run, although successful, didn't last long as Seth Rollins betrayed Ambrose and Reigns to join The Authority. However, the feud with Evolution and the grueling matches at Extreme Rules and Payback 2014 were two of the best multi-man matches in the history of WWE.
