This is just a Lee Sin build I have been working with. I do not know if any of you will have any luck with this but It should help you out. Basically what I am shooting for with this build is to have a nice damage output while also having some resistances so that you do not die so fast. You should end up with around 200 AD, 1.3 AS, 120 Armor and MR, and 14% Lifesteal with unlimited wards. This will really help out having unlimited wards in 3v3. Also 5v5 but it will help in 3v3 more.

As a young teen, Lee Sin was intent on becoming a summoner. His will and dedication were unmatched by any of his peers, and his skill drew the attention of Reginald Ashram, the League's High Councilor at the time. While studying at the Arcanum Majoris, Lee Sin became frustrated with instruction paced for the other students. He spent his free time researching the nuances of summoning in hopes of graduating sooner. He made amazing advances in his arcane studies, surpassing all other students. By all indications, he would have become one of the League's greatest summoners were it not for one terrible mistake. Too impatient, he attempted to test his ability by summoning a beast from the Plague Jungles. What he summoned instead was a young boy, but not in one piece. He barely had time to look the boy in what was once his face before the jumbled human mass fell lifeless to the floor. A League investigation later revealed that the boy's entire village was obliterated by feedback from the ritual.

Lee Sin's talents were so promising that the League was willing to overlook the incident, but he could never forgive himself. He left the Institute and journeyed to the Shojin Monastery for eternal repentance, swearing never to practice magic again. Years later, hoping to atone for his crime with martyrdom, he set himself ablaze as a protest of the Noxian occupation of Ionia. He remained alive in this state, enduring searing agony for weeks. His actions paved the way for a League match wherein Ionia prevailed, but by the time he was doused, his eyes had been burned completely from their sockets. Hailed as a savior, he was reborn, and his will to act invigorated. He joined the League of Legends to continue his atonement with sweat and blood, a true monk's only possessions.

''The actions of one may sunder the world, but the efforts of many may rebuild it.'' - Lee Sin

Marks: I get the Armor Pen Marks because the help Lee Sin with his auto attacks and his abilities too. Armor Pen is very helpful with Lee Sin.

Seals:]/b] For Seals I get Attack Speed because Lee Sin uses auto attack alot due to his passive. These are going to help you out a lot.

Glyphs: For Glyphs I get the Cooldown Reduction runes. Lee Sin uses his abilities very often and having Cooldown Reduction will help alot.

Quintessence: For Quints I get Attack Speed for the same reason that I do in the Seals. The use of Attack Speed really helps his passive.

All together these Quints really help him out and they work for him. If you do not like them then go ahead and change them around to hwo you like.

Masteries: 21/0/9
The reason I get these is because with Lee Sin you want him to have survivability but also Damage output. And with the Last mastery of Offense it helps him out alot. Also it will make it so you have Dmg output while being slightly tanky.

Again you may change these up to fit you're liking. It is really up to you.
