#3 Sting was fine with his mid-card role
When the first episode of Monday Nitro took place, their major Superstars were Hulk Hogan, Ric Flair, Randy Savage, and Sting.
Though all of these four men were a major business changer, WCW wanted to push Hulk Hogan and Randy Savage in the main event level instead of Sting.
With this in mind, WCW decided to pull Sting down to the mid-card. Sting was a top tier talent of the company and he had all rights in the world to bitter about it. However, The Icon was fine with the company's call since he understood what was best for business and willingly decided to step down to the mid-card position.
Also, during this time, Sting was WCW United States Heavyweight Champion and had a very successful reign.
