How to improve with Lee Sin?
I bought Lee Sin, thinking that he would be my main jungler... but the problem is that I am having a really hard time using him. I can clear the camps fine, but I have trouble doing anything that requires fighting, from ganking and counterjungling to teamfights. Also, I generally can play all champions, even those deemed as hard, like Zed or Cassiopeia, but for some reason I have a hard time with Lee.
So: 1 - How to get better with Lee Sin? 2 - Does playing Lee Sin become more fun once you get better with him?
