#1 CM Punk

If you are surprised in seeing his name crop up on the list, please consider yourself as a pro-wrestling fan again. CM Punk was one of the biggest names to leave WWE in 2014.
He had debuted under a straight-edge gimmick and won the ECW and World Heavyweight Titles numerous times. He even led some notable heel factions like the "Straight Edge Society" and the "New Nexus." Cutting a shoot promo on June 27, 2011 episode of Raw, he broke the fourth wall. He had vented out his frustration over Vince McMahon in it and perfectly created the hype for his match at Money in the Bank.
The match received five-star ratings from Dave Meltzer. Moreover, it cemented his status as the "Best in the World." He would later have a 434-day reign as the WWE champion before dropping the title to Rock.
Now, this thing irked CM Punk a lot. Why should he turn heel and lose his championship to a part-timer? Why should the part-timers main event Wrestlemania when the fans tuned in their television sets for him?
He vented all of this frustration at Colt Cabana's podcast. Just displaying an excerpt of it would be an injustice. His last appearance had been at the 2014 Royal Rumble where he was eliminated by Kane. The final nail in the coffin had been hit when he was handed his termination papers on the wedding day!
