I always liked the King of the Mountain match. I think Bischoff and Hogan came in and in an attempt to completely overhaul everything, they got rid of some of the things that worked too.
There was nothing complex or silly about this match. In order to become eligible to "win", you had to score a pinfall or submission. Why is that such a terrible stipulation? If you get pinned or made to submit, you're out of the match for 2 minutes. Not much different from an elimination match, other then the elimination is temporary. Finally, you had to climb a ladder and hook the belt, rather then unhook it. Again, not much different from a standard ladder match.
I, personally, was disapointed to see the match go. It gave several men the opportunity to compete for the World Title that otherwise wouldn't get the chance, and even coined a nickname for one in Jeff Jarrett. It seems rather silly to call him the "KIng of the Mountain" now, with the match no longer in existance. This was one match I wish they would have kept around. It was something unique and exclusive to TNA, and another way they've stripped the product down and made it more like WWE.
