The WWE and Universal title should RARELY be defended on TV. No more than 3 times a year. I've always been a big proponent of the WWE and Universal champion only appearing live on free TV once a month.
The IC and U.S. titles should be defended on free TV once or twice a month, but it changing hands on free TV should be very rare and a big deal should be made about it when it does happen. Same goes for the tag titles and women's title.
Raw and Smackdown should mostly be used to build up contenders, the matches should actually matter. The more wins a guy gets the further he moves up the card to getting a title shot, the more losses a guy gets the further down he moves down the card. WWE also needs to do squash matches with local talent, but do it with more than just the monster heels.
