In-Depth Lee Sin Guides?
I just bought Lee Sin today and I love him (mostly due to the fact I somehow got fed by ksing but let's not mention that). Do you know where I should start learning him? I see some people sustained pretty well after their first few camps where as I am always at 30% hp, I might be taking the wrong route but I heard there's a way to use Lee's passive to sustain so I'd like to know how to do that.
