This guide is a poor attempt to mimmick the top rated Lee Sin guide with minor tweaks to make it "unique". The lack of creativity is sad. You didn't even give it a good title.

That said, you dont have a 6th item, Leviathon is only good if youre not being focused, and can maintain high stacks without dying. Since everyone eventually has a bad game, making this a staple item is a mistake.

Your build sequence and skill sequence are also off. Why build Doran's blade first when it does not build into anything? For 25 gold cheaper you can get vampiric scepter, an item that builds right into wriggle's lantern. You get way more bang for your buck.

As far as skill sequence starting with E means you can slow monster attack speed, which means you take way less damage. At level 2 get W for increased lifesteal. Typically I finish a jungle routine at full health with this sequence. Level 3 with red and blue get Q then gank. They will typically die.

Last bone to pick, you have obsolete seals listed that don't exist anymore.

Bad guide.

Agree with SiAreEx that Leviathan isn't as strong an item as it looks simply because it puts a massive target above your head and once you lose those stacks its worthless.

While opinions are a big part of making different play styles and the guides to go along with those play styles every time I saw "Lee Sin is the best champ evar" it made me want to downvote and just stop reading. There is no "best champ", they all shine in different aspects of the game.

It looks like you made this guide in 30 minutes you have spelling errors all over the place i's that aren't capitalized. While it is fine typing like that in game or whatever when you are tying to share your thoughts people should be able to understand it easily which means having proper grammar.

Other than that its more personal opinion like if you are planning on going for a lvl 2 gank grab Sonic Wave at lvl 1 and after you kill red get Tempest instead of Safeguard. Has higher ganking potential and like you said since the jungle is easier now you can afford to have less sustainability especially with the 12% lifesteal that you start with.

I find it odd that you have a Leviathan becuase Snowball effect items can hevily backfire late game because without any other durability, you're heavily screwed over. i'd replace that and do an Atmog's combo " Warmog's Armor and Atma's Impaler" because this has alot more damage, survivability, and has a minor snowball that you don't lose a third of upon death. I'm going to be brutally honest here and say it really needs some work. Explain a little bit more. and add some icons and such to make it look pretty. =]

I'm not gonna vote because its still a new guide. definatly edit and ill give it another look
