#4 The end of an era

One of the more legendary rivalries in WrestleMania history is Triple H vs Batista, as these are two superstars that have transcended the landscape of professional wrestling, and now they face each other for the last time in their careers, as this match will see Triple H put his career on the line.
This very well could be the last time we see Triple H wrestle because there just isn't any superstar on the WWE roster right now that can legitimately retire the Game. This is a type of match that would be used to open WrestleMania, and if placed anywhere else on the card, WWE would risk having this dream match take place in front of a tired crowd.

#5 Kofi's dream

Kofi Kingston's path to the main event may have been a month-long ride, but to get to that point, Kofi's journey was eleven long years. Eleven years of being stuck on the pre-show, being wasted in the mid-card, and always being portrayed as the highlight reel instead of the man that won the match.
This has been a roller coaster ride of a narrative, as WWE turned the under-rated underdog into the man of the hour as he challenges an excellent antagonist in Daniel Bryan at WrestleMania. It would be a total waste if WWE slotted this match in the same spot the WWE Title encounter between AJ Styles and Shinsuke Nakamura was at WrestleMania 34, as this would be the perfect opener.
