#6 Long Shows filled with meaningless segments
A big reason behind the success of pro-wrestling is the refreshment and excitement that it gives to the viewers. But not everyone can watch the long shows that WWE puts these days.
This year's WrestleMania has the potential to be the longest one ever with a two-hour pre-show and at least a five-hour main show. That's just too much on a go. Especially if there are too many segments without any payoff, the fans won't be happy to sit for such a long show.
Fans have long been complaining about RAW being a 3-hour show and how tough it is sometimes to sit throughout it without getting bored. WWE has a habit of filling random meaningless segments just to kill the three-hour time. That's not something which is helping them, as is visible through the TV ratings.
NXT and SmackDown have a better show format and WWE should seriously consider reducing the run-time of RAW and focus on quality over quantity if they wanna at least maintain their fan base, if not increase it.
