1. Brock Lesnar Vs. Roman Reigns - WrestleMania 31
Despite blood being banned in WWE, Brock Lesnar got some colour in his WrestleMania 31 match with Roman Reigns. It came via the hard way, when Lesnar cracked his head off the ring post. The blood started flowing, and there was no denying that it added something to the match, especially after blood hadn't really been seen for so long. WWE were later forced to deny rumours that Lesnar had bladed, but it certainly looked like he'd deliberately done the hard way. As for the cameras, while they would usually pull away from blood, they in fact focused in on Lesnar. Intentional or unintentional, it made the main event so much more memorable than it otherwise would have been. Seth Rollins' Money In The Bank cash-in meant that Brock lost his title, but in part thanks to the blood, he was so much more over as a monster after WrestleMania 31.
