Ok, in an attempt to become a better LoL player, I'm looking for friendly advice as to how to better counter jungle. I've been playing Kha'Zix, Lee Sin, and Shaco lately.

As Lee Sin I find it pretty easy to counter jungle since he has amazing early game damage and a slippery champion with his Q and W. I try to catch them at Red buff and I can kill them before they use Smite on it, taking them out AND stealing their red. Next, counter jungling with Shaco is fun, able to deal tons of damage if the enemy is caught in the right position, and as Kha'Zix, I can't seem to counter jungle with properly, even though he is my main.

Any tips should help me, so please, tell me other places to ward their jungle besides red buff. Thanks again guys, looking forward to your advice!
