#3 Dean Ambrose and Seth Rollins
This feud has already been done once in the WWE, but that time Dean Ambrose was the babyface and Seth Rollins was the heel of the storyline. This time out it is highly speculated that a feud reversing the roles is about to happen sooner than later.
These two superstars can certainly bring more eyes to the product and can also make fans who are yearning for an Ambrose heel turn happy.
Also, the WWE has consistently teased a crack in the Shield. This can also help in making Intercontinental Championship again relevant. Their feud can have the title on the line even if it does not need it.
This all can be just a fluke and no turn could take place. And it is certainly not happening this early since the Shield's reunion has not lasted very long. Still, we can hope that this feud comes to fruition.
