10 Things WWE Has Forgotten How To Do
2. Less Is More

This sort of goes hand-in-hand with the previous point.
Previously-exciting gimmick bouts such as Hell In A Cell, Extreme Rules, Money In The Bank and TLC have been overused. All are annual fixtures on the schedule, and that strips them of any must-see aura. Then, there's the upcoming Royal Rumble.
Yes, it is cool that WWE finally decided to give women a proper platform on the January tradition starting last year, but it comes at the cost of over-saturation. January's pay-per-view now has two 30-person battle royals filling time, and that lessens the impact of each one an an individual spectacle.
As for TV, Raw has slumped from tight-knit two-hour thrill ride to a three-hour yawnfest that creative blatantly struggle to fill with effective content. The phrase, 'less is more' doesn't mean much to WWE nowadays; they're more interested in hurling as much product as possible at the viewer, and that's clear across TV and pay-per-view marketing.
