These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Arc Fatigue: The nWo concept lasted at least a full year longer that it should have. By the time it was "Black & White" versus "nWo Wolfpac", it was already getting tired. The group ended up being revamped twice more before WCW's ultimate demise.
Not only that, but after the nWo finally died, there was not only one more massive heel stable (The New Blood) that had multiple sub-stables with in it that also split apart and feuded, but the last 2-3 months of WCW was also anchored by a big heel stable (The Magnificent Seven) running roughshod over the company. The New Blood actually had more members than all forms of the US nWo (including the WWE version) despite only officially lasting about 3 months.
Creator Killer: The infamous Fingerpoke Of Doom put WCW on life support; David Arquette's run as WCW champion was simply the death knell. Ironically, Arquette himself escaped the debacle with his reputation unscathed, the reason being that Arquette himself was a wrestling fan and had protested the decision, only complying due to his contract — it helped that the money he earned from it he donated to the families of several paralyzed and/or deceased wrestlers (including the late great Owen Hart). Everyone else didn't, but none more so than Vince Russo, who was so universally despised that the entire WWE creative department threatened to resign when Vince McMahon brought him back briefly in 2002. Nowadays, the only wrestling company that will take Russo on is TNA, mainly because they're run by old WCW guys.
Ensemble Darkhorse/Just Here for Godzilla: The Puroresu and Luchadore stars who put on phenomenal matches every night, even to the very end, well, until they all realized they'd never get pushes and started leaving in droves.
The entire Cruiserweight division which included both styles above but also guys like Chris Jericho, Chris Benoit, Dean Malenko, and Billy Kidman were the wrestlers who opened up the night to pump up the crowd and were usually the best match of the night. Despite this, crusierweights were often disregarded in terms of getting a push. In fact, many mentioned that they would get punished for getting over.
In hindsight, Buff Bagwell made a lot of media appearances outside of wrestling and showed up on a lot of merchandise for somebody who never won a singles title and never really was able to rise beyond the midcard. He seemed to pick up a few fans because he was so damn goofy.
Hilarious in Hindsight: For a period in late '96, Ultimo Dragon defended the J-Crown, a collection of cruiserweight/light heavyweight championships from various promotions unified into one collective (and cumbersome) title. At Starrcade '96, he defeated Dean Malenko and added the WCW Cruiserweight Championship to the J-Crown in the only time the J-Crown collection was seen on American television. What makes this so hilarious? One of the titles that made up the J-Crown was the WWF Light Heavyweight Championship, note When first created, the Light Heavyweight Championship was defended almost exclusively in Mexico, making it a WWF title pretty much in name only. Over time, it made its way to Japan, where it eventually became part of the J-Crown. When the WWF got it in its head to start a dedicated cruiserweight division in late '97, they went through the books and found out they already had a perfectly good Light Heavyweight Championship belt they'd given out on loan for over a decade and had no idea where it was! After some searching, they tracked it to New Japan Pro Wrestling and finally got it back for their inaugural tournament. meaning that Ultimo Dragon was a legitimate WWF championship titleholder and was legitimately defending that title on a WCW pay-per-view, and neither promotion realized it until months later.
Others with creative control in WCW: Randy Savage, Scott Hall, Kevin Nash, Bret Hart. Of that group, the only one to really abuse it was Nash. Randy Savage in particular seemed to make it a point to OVER sell for guys and look bad in storylines in 1995/1996, plus was completely responsible for the entire angle with DDP that catapulted DDP into super-stardom. Watch early Nitros and be amazed at how Macho would spend a whole match getting absolutely crushed by relatively unknowns like Scott Norton, Chris Benoit, Kurasawa, Hugh Morrus, and Craig Pittman, while Hulk Hogan was busy having the entire Four Horsemen beg off from him and beating up EIGHT members of the Dungeon of Doom by himself.
Shocking Swerve: Arguably the trope namer. Inarguably, it is one of the reasons why WCW went out of business.
