If they're gonna have a WCW One Night Stand then you got to have matches and segments with tons of screwups in them. Read the Death of WCW and you'll find out.
Like in the main event for the WCW One Night Stand, have a first blood match with, lets say, Flair and Hogan, and have Flair get cut open, but the match continues, then have Flair whack Hogan with a lead pipe and bust Hogan open, then have a run in from the NWO, and have Flair knock Hogan again in the head with the same lead pipe he did earlier and get DQ'ed. WCW was like that
