#3 More WWE and Universal championship matches
A problem for Raw is that because Universal champion Brock Lesnar is part-time, so is the title, but even on SmackDown, the WWE championship is rarely defended. That isn't to say the championship should be defended every week on Raw and SmackDown. Instead, it should be reserved for special occasions. Having them too regularly can devalue the titles, but having the titles on the line every now and again can add more interest to the product.
Teasing potential title changes on WWE's two main shows could increase viewership, interest and generally make the shows more compelling for its spectators. If the product is to be stronger overall then this has to start with the weekly shows Raw and SmackDown. Title matches on these shows can be a way to attract new or casual fans to watch the product more regularly.
As with any form of entertainment, there needs to be an element of unpredictability with each show. The 'wow' factor that can capture the audience, by having title matches and even title changes of Raw and SmackDown, it will make the shows 'must see' television, as it did during the height if WWE's popularity in the Attitude era.
WWE no longer has a rival to go up against, as it did with WCW, so they do not need to push the envelope as much, but adding drama to their weekly shows can give the product the boost it needs.
