#3 Quick elimination
For some reasons, WWE has a weird liking to have someone break Santino Marella's record of breaking the least time spent in the Royal Rumble. In 2009, Santino Marella was eliminated by Kane in a record one second.
However, since then, WWE has tried to break this record multiple times but has failed on each occasion. The last attempt was at the Royal Rumble 2018 where Sheamus was eliminated in just two seconds. Although the spot might be hilarious if pulled off right, the fans aren't always happy about it.
Royal Rumble 2019 will also be the 10th year anniversary of Milan Miracle's feat and considering WWE's love for this particular spot, we will probably see WWE doing it once again. Let's hope someone finally ties or breaks the record so that WWE gives up on this idea.
