Hello Everyone, I am FaTExNiTE known in ranked queue for my Lee Sin jungle and Solo Top. Last season I made gold and this season I will update the elo I play him at, this guide will specifically show the builds and strategies against many of your opponents in solo top.
Gold Divison II Rank 3 in Amumu's Liberators.

Lee Sin is a very versatile champion with 2 leaps, a knockback, and an aoe atk & movespeed debuff.
Lee Sin excels at dueling, using his lifesteal and spell vamp, he will certainly be a champion that is stronger than most.

Pros:

[*] Energy character
[*] Attack Speed Inc Passive
[*] Abuses and Snowballs Lane if you manage to outfarm or get early kills on your opponent
[*] Q -> R -> Q is one of the strongest execution or dps moves
[*] Safeguard / Iron Will gives you high amount of sustain in lane from Ranged bullies.

Cons:

[*] He is blind, making it harder to land Sonic Wave
[*] If you are getting abused, maxing your Safeguard/Iron Will will drastically decrease your damage
[*] Slight fall-off in damage late game.
[*] Not a character used for his high DPS

This section will go farther in depth compared to the notes I had left on the cheat sheet. If you look back, I reccomended running 3x Attack Damage Quints, 9x Marks of Attack Damage, 9x Seals of Armor, and 9x Seals of Scaling Magic Resist. Of course this is standard unless you are playing against a few other champions who would deal purely one type of damage, e.g. Tryndamere. If you happen to roll up against a Tryndamere, Garen, Renekton, Talon, Riven, or any high physical damage bruiser top lane, You would want to replace your 3x Quints of Atk Damage to 3x Armor Quints, giving you a complete bonus 25 Armor instead of the 13 you would have gotten if you just ran armor seals. Next I want to discuss Flat Magic Resist Glyphs. Many people are tending to switch over to flat magic glyphs to stop a lot of the early game damage from the AP Mid & Jungle ganks. I take Flat Magic Resist over Scaling more often than never. The fact is, scaling magic resist will not beat out the flat magic resist until around level 9, which then you should either be able to stomp your lane or be stomped. Of course you might want to take scaling if you are running the Heavy Armor version of the rune page. That is all to say on that note, next is masteries.

Ah masteries, one of the most conflicting things inbetween people's builds and opinions. The change into Season 3 masteries has made quite the impact on many champions. Lee Sin is no exception. As I play top lane Lee, I run 21/9, as the bonus "Execution" mastery has great synergy with his resonating strike, as it deals more damage the more health the enemy has missing. When you take the Executioner buff it gives you an additional 5% damage when they are below 50%. When you are going against strong champions who are very aggressive, you can run 9/21/0, grabbing reduced champion damage, bonus health, armor, magic resist, tenacity, and health. People ask me all the time, "Why don't you take legendary armor?!", that answer is simple; legendary armor only gives you your 2/4/6% BONUS armor. Now that Lee Sin has had his armor bonus from Iron Will taken away, the Legendary Armor mastery is not even a decent mastery. Let me calculate this for you, Bulwark Armor + Wriggles Armor = 50 Bonus AR, Plus 13 Armor from your runes, you would get 63AR, The mastery would give you 3.78 Armor, or roughly 4 armor at 3/3 for Legendary Armor. "Why don't you run 0/9/21 or 0/21/9??", wtf no.
