10 Mega Superstars who quit WWE in their prime

#9 CM Punk

One of the biggest departures from the WWE in recent times is that of CM Punk, who had a cult following among the WWE Universe.

Punk quit WWE in 2014 and cited several reasons for leaving the company. The former WWE Champion was unhappy at how WWE doctors were lax in the treatment of an injury to him. He was also displeased at being paid lesser than other Superstars on the roster, while one of the other important reason for his departure was his unhappiness at the storylines he was involved in.

He was also unhappy at not having main-evented WrestleMania, despite being one of the most popular Superstars on the roster.

After quitting WWE, Punk switched his sights to UFC and MMA, but has lost both the matches that he's been a part of, with many believing that he's not cut out to being a UFC fighter.
