#1 Hates change
Let's be honest here.
The WWE Universe dislikes change in any form and constantly complain about after every edition of Raw and Smackdown Live. Beyond that, they love to criticize any new idea WWE comes up with, even if it's a good one. If nothing else, WWE fans just shouldn't be taken as seriously as they used to be.
Think about it! WWE did The 24/7 title, brought in the wild card rule, moved Roman Reigns to Smackdown Live, took Brock Lesnar out of the title picture and fans still aren't happy. They are also so caught up in their dislike of WWE that they will put down the company and talk up any viable alternative.
Not only is that making the base extremely problematic, but also extremely biased as well. It's as if WWE could continue to do whatever the fans want and they would still find something wrong with it!
