About a year ago I was the guy in the gym trying to create the most ridiculous attribute based techniques you could imagine and often times they would work just out of the suprise factor when I'd full nelson someone with my legs or go inverted for no reason. This stage helped me learning something. The shittier the technique the faster everyone is to negate or counter it. Now I'm in a stage where I'm only doing techniques that are high percentage and my focus is to increase the positive outcomes of already time proven techniques. My goal isn't to win, it's to win without breaking a sweat and to give my opponent no room for hope. If it wouldn't work against Marcelo, Jacare, or Roger why bother putting it into your game? All of this being said what techniques do you feel are too high risk or violate what Jiu Jitsu should be; conservation of energy. I'll start. I feel the basic armbar from guard is an outdated technique. Each step in the technique has an extremely effective counter. Sure there are plenty of recounters to those but unless you're specifcally doing the armbar to setup say...a flower sweep it's a flawed technique. I've only ever see someone pull it off on someone who was either A) much weaker or B) much less experienced. Do I think it's impossible to setup an armbar from guard? No, but I do feel the traditional armbar should be updated or discarded.
