I can't rep you anymore. Expect some the next chance it allows me to. You hit the nail on the head.
You missed 1 thing: The Cruiserweights.
You right, that was a big omission from my part.
Basically, WCW was the only company that you could see a division strictly devoted to the cruiserweights in the US. And before somebody says they stole Mysterio, Konnan, Psychosis, Juventud, Jericho, Benoit, Malenko & Guerrero, you've only named about 15-25% of the cruiserweight division. Further more, their cruiserweight/light heavyweight division really got praise due to Brian Pillman and Jushin Liger. They're the reason the division even existed but I guess we're supposed to go off revisionist history.
If people still can't see what made WCW so great/different from the rest, it's because you've never watched it or you let WWE tell the story of the history of WCW.
