#4 Started rebuilding the tag team divisions
Since WrestleMania, the Raw and SmackDown tag team championships have barely been featured on TV. Curt Hawkins and Zack Ryders' only meaningful appearance was a loss to the Viking Raiders. During the match, the champs apparently shared the secret to never being on TV with Erik and Ivar and so they also disappeared, with their victory over the champs never mentioned again.
On SmackDown, Daniel Bryan and Rowan won the vacant titles and vowed to start a tag team revolution in WWE. They started on this valiant quest by losing to the Usos on the Money in the Bank pre-show and joining their Raw counterparts off TV.
However, this week served as a positive first step to rebuild the tag team division on both shows. On Raw, The Revival won the tag titles which instantly gives them more credibility. As much as you might lament the titles being passed around constantly it is clear that WWE was never going to push Hawkins and Ryder as strong champions. At least The Revival has some star power and will always be a big deal to a hardcore section of the fanbase.
On SmackDown there wasn't a reset but a sign that a storyline is gaining momentum. Heavy Machinery beating two jobbers isn't the most inspiring way to build a program but it signifies that WWE has some sort of direction for the titles.
This was a program at risk of being dropped in the midst of the champions losing random pre-show matches and disruptive Saudi Arabia trips. By returning to it, WWE can now start building something on SmackDown out of a division that is admittedly lacking teams.
