i dont think you should say not enough nado, you can win without using nado at all lol. instead of saying you should use nado more, you should look to when you can use nado effectively.
dont rush in with your tornados. only use nado when you're already close, that way you can run away if necessary/pressure shields or whatever.
dont be so set on one particular option. if something doesnt work the first time then it wont work the 2nd or 3rd either lol. just adapt. mix it up.
i think you should watch your video yourself and analyze WHY **** you did wasn't working, WHY you got hit in that situation. and dont just analyze that, see what led up to it. i think its more important for people to realize things in their own then to have someone tell it to them. but I gave you some things to get you started.
