#4. Triple H vs CM Punk - WWE WrestleMania 30
CM Punk was the self-proclaimed "Best In The World" during his time in WWE and was looking to main event WrestleMania in 2014. The former World Champion had been working hard as part of the company for several years and hoped that the company would grant him the opportunity to main event the biggest show of the year at WrestleMania 30.
Punk was instead scheduled to face Triple H on The Grandest Stage Of Them All and wasn't happy when he was informed that he was being snubbed for the main event once again.
Punk walked away from the company following the 2014 Royal Rumble which caused WWE to change a number of plans for that year's show. Daniel Bryan was pushed as the main eventer in Punk's absence and went on to wrestle Triple H at WrestleMania instead, which meant that his originally planned match with Sheamus was scrapped.
Batista and Randy Orton were the two men scheduled to main event WrestleMania but WWE made the decision to include Bryan in that main event match after he was able to defeat The Game on the same night.
