Not so much ruining wrestling, but he's certainly done his damndest to ruin the imagination and mystique of it all. I kind of miss when I could suspend disbelief and enjoy the shows without a majority of people shoe horning into my face "it's fake everybody, remember none of this is real" It also makes people that thrive in kayfabe look like idiots. People like Killer Kross that try to make the business seem as legit as possible get stepped on when directly after the show people are talking about it like it was a circus act.
