Benoit is an obvious choice. Wrestling was weird afterwards.
This other one didn't traumatize me as such, but Punk leaving. I think if it had not been for Bryan, I might have stopped watching completely in 2014. The product was pretty bad after Batista won the 2014 Men's Rumble, I had just about given up on it. I was sick of the fans being treated like garbage, and all my favourite guys got tossed out the rumble like they meant nothing. Then news came out Punk walked out, and I just lost all motivation to watch. I'm glad I didn't stop watching looking back, that was one of the best WrestleMania events and probably won't be topped in the current era.
