I hate this idea, I absolutely hate it... If you think WWE Championships don't have prestige, then just wait until that idea starts to get "the same old crap" routine. What's special about PPV's for the majority of the fans? It's the place where championships get defended, the place where wrestlers fight to get their due after a rivalry in the weekly program.
If you give a championship match per week, you are transforming the title into crap. It's not exclusive anymore, it does not have value anymore. Back in the days, Golden Era, where the championships had value, champions would only defend his titles at SME or WWF PPV's. It's rare, really rare the championship match at weekly television, and that's why championships had value.
I think that WWE gives us way to much championship matches at SmackDown/Raw/ME. It's supposed to be special, I want to pay for a championship match, because every time the title changes, we see something new, but it made sense. I will not pay for a championship match, if I am sure that two weeks after the PPV I'll see the champion defend again. It's basic marketing, and quite frankly it's what pro-wrestling should be all about. WWE needs to get more old-school again. Reigns (not Roman) should have meaning, I am not a CM Punk crazy fan, but I enjoyed his title reign because he didn't had to defend his championship outside PPV's, even though he did against at least three other people on Raw (Henry,Cena and Ryback).
