#2 Segments involving Legends

One of the most common themes in WrestleMania for the past few years (barring WrestleMania 34) has been the involvement of WWE Legends during the show as part of in-ring skits/promo segment. Names like The Rock, Stone Cold Steve Austin, and Shawn Michaels have been a part of some of these segments.
Although these segments are a great way of generating that huge nostalgia pop and add more star-power to Mania, they (almost every time) involve the legends absolutely burying a younger group of talent, which isn't how the company should utilize their young and upcoming superstar, in our opinion.
In addition to that, some of these segment stretch for far-too-long, which results in some matches on the card being cut short due to time constraints. WrestleMania should be all about showcasing the current crop of talent and not burying them at the hands of part-timers and Legends of the business.
