5) Hour Long Ironman Match: This match has always kind of split viewers. Some hate the idea of a match going for an hour and others think it can be art work. While I find the Bret Hart/Shawn Michaels one to be overrated, the Rock/Triple H and Brock/Angle ones were fantastic. I'm sure there are more I'm forgetting about but when done right the Iron Man match can indeed be excellent. Most of the time, the thirty minute ones are better, but sometimes I miss the hour long battles.
4) First Blood: I'm not a barbarian who needs blood to enjoy his wrestling, but I used to think this was a cool match type. Now, we get Hardcore, Extreme Rules and Street Fights, which all mean the same thing. This was similar but only ended when one man was busted open. Obviously, I see the reason why it's gone as athletes don't need to blade, but it was fun while it lasted.
3) Ultimate X: Granted, I've only just gotten back into TNA when they moved to Destination America, so I'm not completely sure if this match is gone but I haven't really heard anything about it for a long time. Ultimate X is obviously a match for high spots but it was so much fun and part of what made me interested in TNA in the first place. It made them different and is something they never should have gone away from.
2) Best of Series: Whether it is a best of five or a best of seven series, one of these can add prestige to a title. Or even a feud between two guys trying to prove who's better. Booker T and Christ Benoit had a classic series in WCW and I remember TNA doing one with Beer Money and the Motor City Machine Guns. Hell, the WWE tends to book a million rematches anyway, why not have some be a series? It would give them more meaning. I would have rather watched a series of some WWE rivalries instead of rematch after rematch.
1) War Games: I know that there are a lot of things the WWE doesn't want to use from WCW, but War Games is one they should have. The concept of War Games was always cool. The two ring part can be tough as some arenas can't really fit it, but this could work in the Hell in a Cell environment. It would have worked multiple times since WCW closed, most recently right after WrestleMania XXX. I think the Shield and Daniel Bryan vs. the Authority would have been fantastic.
