Only Chapter(summary of play)Lee sin is master top; OP. You want to not let your enemy out cs you(EVER) don't make serious trades until full kit. You will want to be precise with your kicks, it may mean free double kills top lane. ALWAYS ignite+ult combo if you aren't sure of kicks, it's an easy escape, usually providing for you to get a kill when ganked. NEVER dive if you aren't sure on jungle.
Happy Hunting, summoners.
