#1. Not a genius - the Wild Card concept

The most recent addition to this list, you're probably wondering why this was added, especially since it doesn't have much relation to the other points. However, it was frustrating for fans not only because the concept itself was terrible, but the fact that Vince McMahon called himself a genius during the show and even had Renee Young shill for him, constantly referring to it as a "great idea".
The issue with the Wildcard concept is that it takes away the specialty of cross-brand appeal, which were far and few in between. Moreover, it's a very clear indication that the brand split is slowly coming to an end sooner rather than later.

Hopefully, it becomes one of those things where WWE realizes that it's a bad idea and scraps it silently. The brand split must remain to give each brand its legitimacy.
