#3. Tag team division
WWE's main roster has made it a habit to destroy their tag team division, The revival, Ascension, Authors of Pain, Sanity - the list goes on. Coincidentally, these tag teams were outstanding in their time in NXT. Ascension had a long run with the tag team titles. The revival was one of the best tag teams. Authors of Pain and Sanity were having all-out wars against each other. However, once they reached the main roster, they have been watered down and started losing a lot.
Ascension is now Curt Hawkins of tag team division, The Revival is an afterthought. The main roster creative clearly does not have any plans for AoP or Sanity. The only solace is the booking of tag teams on Smackdown, which is slightly better.
On NXT, however, things are way better. The tag team match between Undisputed Era and Moustache mountains was rated 5 stars. At every NXT takeover, the tag team title match is a special attraction. With the war games set to return in November, it is safe to say that the NXT tag team division is miles ahead of RAW or SmackDown.
