#2 Made the fans hungrier for a changing of the guard

WWE has been excellent at creating substantive change throughout its programming over the last couple of months, but the one thing they have never given up on is having Brock Lesnar as WWE Champion. Outside of a few stints without the belt, Lesnar has been either WWE or Universal Champion for the better part of the last 3 years.
Brock, although he has had some stellar matches recently along with a captivating feud with Rey Mysterio and his son, is still only a part time performer and thus isn't really the fighting champion that the fans are looking for. Interestingly enough, it seems like WWE knows that and are using it to get the crowd ready to cheer for the right person. The WWE Universe enjoys watching Brock take people to Suplex City, but as was evidenced by the gigantic reaction to Drew McIntyre eliminating the WWE Champion from the Royal Rumble, they are ready for something new.
In all honesty, the WWE Universe is sick of the status quo and many are tired of Lesnar holding the title picture hostage. That's why the company appears to be building up McIntyre to finally take Lesnar off of his perch. We'll have to wait and see what happens at WrestleMania 36, but good money is on Drew McIntyre becoming the next WWE Champion.
