#1. CM Punk gets the perfect send-off that he deserves
In 2014 when CM Punk departed from WWE, fans around the world were left stunned by his decision. Several members of the WWE Universe made it known that they weren't too pleased with the events that had transpired and there was also no surprise to the fact that Punk had left WWE on bad terms.
Shortly afterward, CM Punk himself revealed the differences he had with WWE that led to his departure from the company. With that being said, a return to WWE would also lead to the perfect send-off for Punk.
Knowing that 'The Second City Saint' is currently in his 40s, it would be quite unlikely for CM Punk to continue his professional wrestling career after another run with WWE.
Hence, the former WWE Champion will receive the perfect send-off and the get the perfect retirement, if he returns to WWE and decides to end his career on a high note with the company where he made all the name for himself at one point.
After all, given how much Punk has dedicated to the professional wrestling industry, he certainly deserves a proper farewell.
