#4 Lesnar's reign has been far too short
A lot of people were upset that Brock Lesnar became the WWE Champion on the inaugural episode of SmackDown on FOX. And this is because Kofi Kingston, who'd been booked as a strong Champion until that point, lost in a matter of seconds to The Beast Incarnate. Since then, he's defeated Cain Velasquez at Crown Jewel too. But that's about as long as Brock Lesnar's reign has been thus far.
We often complain about the fact that WWE does not invest too much time into their Champions and whether or not that rule applies to Brock for the Internet Wrestling Community, it makes sense for him to reign as a formidable Champion for some time before losing the title. Because when a top star eventually unseats him from the throne, it will establish the said Superstar as a big deal and give him the legit rub!
