I love the Elimination Chamber match and I am glad it is only used at one particular PPV to me that makes it more special. I think it is one of the more original ideas for gimmick matches that WWE has come up with in the past couple decades. So I definitely don't want to see the match disappear, but I would have no problem with the EC PPV exiting stage right along with about half a dozen of the other PPVs on the schedule.
If I were running things and with the Network on the horizon I would make the year long events look something like this:
January: Royal Rumble PPV, winner of the Rumble match faces champion of choice at Wrestlemania.
Febuary: No PPV, but a live special on The Network or USA with PPV level and quality matches. Possibly have one of the big gimmick matches like Elimination Chamber, Hell In A Cell, TLC, or Championship Scramble (which they don't use enough) on this special.
March: No PPV, but a live special on The Network or USA with PPV level and quality matches. Possibly have one of the big gimmick matches like Elimination Chamber, Hell In A Cell, TLC, or Championship Scramble (which they don't use enough) on this special.
April: Wrestlemania PPV, The biggest PPV of the year of course. Balls to the wall, huge epic dream matches would fill the card, no fillers, no bullshit, titles, careers, and reputations at stake. Make every match matter, make everyone care again, really make the event a spectacle that will always be remembered.
May: No PPV, but a live special on The Network or USA with PPV level and quality matches. Possibly have one of the big gimmick matches like Elimination Chamber, Hell In A Cell, TLC, or Championship Scramble (which they don't use enough) on this special.
June: King of the Ring Live Special on The Network or USA. Have qualifying matches on RAW and Smackdown, during April and May to set up a one night 8 man tourney for the King of the Ring. The winner of the King of the Ring would get title shot at champion of their choosing at Summerslam.
July: No PPV, but a live special on The Network or USA with PPV level and quality matches. Possibly have one of the big gimmick matches like Elimination Chamber, Hell In A Cell, TLC, or Championship Scramble (which they don't use enough) on this special.
August: Summerslam, I would basically make this the Wrestlemania of the Summer. Maybe just not quiet as much of a spectacle as WM, but definitely would be nothing but major feuding ending matches, between the top guys, not much filler, with a lot more flare.
September: No PPV, but a live special on The Network or USA with PPV level and quality matches. Possibly have one of the big gimmick matches like Elimination Chamber, Hell In A Cell, TLC, or Championship Scramble (which they don't use enough) on this special.
October: Halloween Havoc, another PPV level live special on The Network or USA, that had a definitive theme (that being Halloween of course). Could be a sorta tongue in cheek almost silly show. Just make it something real fun and not as serious as the other specials or PPVs.
November: Survivor Series, the last PPV of the year. Go back to the traditional formula of the Tag Team Elimination Matches. This would be the PPV that would give the younger up and comers and mid card guys on the cusp of entering the main event the chance to shine. Have maybe one or two title matches on the card but mostly focus on the traditional Survivor Series style matches.
December: No PPV at all. No Live Special at All. Give the guys a chance to rest, recoup, recover, and spend some time with their families for the holidays. This could be when the pre-taped Tribute to the Troops specials could air or have a Best of the Year special where the best matches of the year that may have been missed by some could be seen again. Give it a whole Year in Review kinda feel, while gearing up for what is to come in the next year.
