in my own opinion they shouldnt have any gimmick PPVs, and if they have to have at least one it can be Extreme Rules, just because the name of it itself tells you some crazy matches are going to happen. But when you have a PPV for Hell In A Cell, MITB, TLC, Elimination Chamber..it kills the hype and the shock and intense value of it.
Like for example, the Hell In A Cell used to be a match where great feuds came to an end, now its a tradition where we have like 2 HIAC matches a year. We used to have it either once a year or even every other year, and when someone would say "One on One....in HELL IN A CELL!!" The fans would erupt, but now we know every year when it's coming and we know which feuds will be in it so there is no shock anymore. Like this year we KNOW 100%
WWE Championship Hell In A Cell
CM Punk vs John Cena
Now if it was called 'Vengence" and we were told like 3-4 in advance "Hell In A Cell!!" I would be excited, but when this last PPV ended, i knew from then it would be punk cena HIAC.
