#4 Forgettable matches with men like Brock Lesnar

Dean Ambrose is a subtle and nuanced performer. While he is capable of brawling and hardcore antics, he is also an underrated ring technician and submission artist.
Perhaps that is why he has been so frustrated when working matches with men like Brock Lesnar. Their title match was considered a major disappointment, and Dean placed the blame squarely on the shoulders of the Beast Incarnate.
During Stone Cold's podcast, the Lunatic Fringe made certain to point out that "Brock Didn't want to do anything," meaning that Lesnar was interested in only collecting a quick paycheck and not at all with making the match memorable or entertaining. Dean has often been forced to work with such talents, while Seth Rollins and Roman Reigns faced more worthy opponents. This frustration could be one of the reasons Dean Ambrose wants to leave the WWE behind.
