This is my first guide and I wanted it to be on the most funnest champion in the game. I dont claim to be a pro at LoL but I Think I have enough experience with lee Sin to make a guide on him :-).

Pros:
Insane Early to Mid game
Insane Ganks
Awesome Counter jungling
Spectacular Counter Ganking
Great Mobility
Game Changing Ult If played right
Cons:
Difficult To master
Falls of late game

Make sure your using his passive to full effectiveness when using lee. If you didnt know already his passive makes his atk speed go up after using an ability. So a good way to farm the jungle is
e basic attack x2 e basic attack x2 w basic attack x2 w basic attack x2 then finish with q.

The reason I max q first is to maximise Lee's dmg but I make sure to secound a secound point in e early for the slow .I then max w secound to maximise dueling potential and upgrade ult whenever i can.

To gank as lee you can either land your q on your opponent go in OR your ally goes in you w towards them slow the enemy put your q on the enemy try wait for a flash then q again

Thank you for Reading My first Guide all kinds of constructive criticsm and praise is welcome :-D
