#3. SHOULD END: Punk won't be around forever and hasn't wrestled high profile stars yet
CM Punk is 43 years old and realistically won't be having his best performances 10 years from now. Wrestlers like Sting and the Rock 'N Roll Express have proven that elite talents can go well into their 60s. However, this differs from athlete to athlete.
Fans might still enjoy a grayed CM Punk wrestling, but at this stage he hasn't gone against anyone older than 30. The Best in the World could still have dream matches against the likes of Christian, Jon Moxley, or Kenny Omega. His feud with MJF is preventing him from branching out, so it's time it comes to a close.

#2. SHOULD NOT END: The storytelling between the two is impressive and could yield more stories
As showcased in the now-famous photo on Dynamite, MJF and CM Punk first met when Friedman was still a child. Their unlikely reunion years later one of the most interesting callbacks in pro wrestling history.
Punk and Friedman also have polarizing personalities. With both being top talents on the mic, their face-to-face promos have made for captivating television.
At this stage, the feud is largely based around Friedman wanting Punk's attention and not getting it. However, the two are both magnificent storytellers in wrestling and could create even more compelling stories going forward.
#1. SHOULD END: The dog collar match is a historic feud-ending stipulation
The first televised dog collar match occurred in 1983 between Roddy Piper and Greg "The Hammer" Valentine. That bloody bout became historic, and since then, the stipulation has been used either to pay homage or to showcase the seriousness of a feud.
Dog collar matches do not happen often on television. They are brutal affairs and have been known to cause permanent damage and shorten the careers of wrestlers. For Punk to name this stipulation is a big deal.
The rivalry between CM Punk and MJF should finally end after a historic match instead of being dragged on. With as heated as this storyline has been, it should be remembered as one of the great feuds in AEW's history rather than something that continued to the point of boredom.
