Copyright: WWE Royal Rumble 2014 Blu-rayPhilip Jack Brooks, known to fans and friends as CM Punk, has been one of the most divisive figures in professional wrestling for quite a long time now. Never afraid to speak his mind, or backward about coming forward, hes rubbed a lot of people up the wrong way for a variety of reasons. But the most polarising thing hes ever done more so than turning on Ring Of Honor fans in the first Summer Of Punk, more even than his notorious worked-shoot promo in June 2011 which led to the second Summer Of Punk in WWE was abruptly leave Monday Night RAW on 27th January 2014. And he didnt come back. Punks played with this kind of thing before, so a little boy who cried wolf reaction on the part of wrestling fans the world over was understandable. It was a work, they nodded to themselves wisely. They asserted that hed be back for the next RAW in his hometown of Chicago. Then, when he didnt show up, they were sure hed be back for Wrestlemania XXX. Think of all the money hes missing out on, they said. Hell come back for the biggest show of all, they said. Of course, CM Punk didnt come back. And the longer it went, the more people stopped predicting when hed come back and started sniping at him for leaving. Even the staunchest of Punk supporters have begun to feel a little bit narked over the last few months. Where is he? With CM Punk chants dying out and life in WWE going on without him, his approval rating appears to be at an all time low, both with the crowd and with the WWE roster that used to think of him as a mentor figure. Here are a dozen of the reasons why that might be.
