#4 His mic skills are untouchable and he genuinely personifies everything that is 'Ruthless Aggression'

Ever since the Shield debuted on Raw and took the wrestling world by storm, Dean Ambrose has always remained the most significant member of the iconic faction.
Vince McMahon also addressed in the Stone Cold Podcast that the Lunatic Fringe happens to be the one who is certainly outshining everyone and reaching for that brass ring.
The fact that he pushed Ambrose as the top priority before Roman Reigns and Seth Rollins prove that the Boss definitely sees money in the Lunatic Fringe.
While John Cena was the last of his kind, Ambrose catapulted himself to the top of the wrestling industry and personified everything that is 'Ruthless Aggression'.
Since Roman Reigns was handpicked to be the company's Golden Boy, it was Dean Ambrose that built his reputation organically and became the most intriguing member of the Shield.
