Worst thing that ever happened to pro wrestling was losing WCW.
It was a dark day, and I'm saying that as someone that pretty much gave up on WCW and watched WWF on Monday Nights exclusively by that point.
Its a shame that it happened, and I wish WCW had survived in some capacity. All artforms are better when there are other options. I don't want just Marvel. I want DC, IDW, and whatever other Indy brands are out there. I don't want just Disney films, but WB films to do well too. I don't want just Game of Thrones. I want Better Call Saul, Rick and Morty, Walking Dead, and various other shows as well.
Losing WCW just seemed to kill the spark that made watching Wrestling a euphoric experience. I'm not even really sure how to explain it, but something was missing. WWE became the overbloated and formulaic show that it is now, which certainly didn't help, but its why I encourage people check out the Indys, ROH, NJPW and whatever else is out there because variety is the spice of life.
However, nothing has quite been able to replace having a wrestling brand on par with WWF producing content on a rival network and going to head on Monday Nights. We'll never get that back probably, and I guess WCW is just too big a void for other companies to fill.
Still though, I miss having it around, even towards the end when the show was garbage. It was nice to know that if things didn't work out in WWF, the guys had somewhere else to go and vice versa. Now, that bargaining posture has been taken away from the talents and it is basically WWE saying "Take what we give you or there's the door". Hopefully AEW gives a little more power back to the talents in that regard, but we shall see.
