#2 Worst: Reliance on part-timers
WWE's worst habit has to be to ignore the wealth of talent it has on hand and instead, push its part-time Superstars. You have someone who gives it his all like AJ Styles or even Seth Rollins, and right now the WWE Champion is Brock Lesnar. This has been the case for most of the decade, with Lesnar winning his title and disappearing for months at a go.
There's also the habit of bringing in Superstars from the mainstream world, from Tyson Fury to Cain Velasquez and putting them in top spots against their top stars.
Braun Strowman even had to suffer a humiliating defeat to Tyson Fury, a Superstar who will not be a part of the WWE roster on a regular basis at all. And of course, who can forget the disaster that was the Undertaker vs. Goldberg match at Saudi Arabia?
This is the reason that WWE hasn't been able to create a Superstar in the same league as John Cena or Batista this decade. When Superstars who're past their prime get the featured spots, what hope does the full-time roster have? I get the idea of bringing in crossover fans, but I'm not certain that this strategy always works.
