I'm sure I'm going to echo what's been said:
Too much wrestling- there really needs to be an offseason now because there's just too much of it. WWE is saturating a very niche market and it's making their wrestlers and their events feel less special.
Smackdown needs a reboot ASAP
They need to get back to characters and stop having matches just for the sake of matches. Showcase characters and stories
Allow cats to flourish rather than deeming who's going to be on top of the card. Let the fans decide and work from there
Things need to feel more organic than they do and less predictable. The build up to Mania 15 is a perfect example of this: McMahon won the royal rumble, which yes is ridiculous but it served a story purpose. From that one shakeup at the rumble, we got Austin vs McMahon at an in your house, which led to him getting his spot against Rock at mania, while also incorporating the big show and mankind. It told a compelling story that didn't feel predictable and made sense based on everyone involved.
