Hi guys, this is my first guide so don't blame me or my english-knowledge too hard, thanks !

I just tried to give the new Champion a try, so this guide was created.
My experience isn't that great but this build works well on normal rounds for me.

In my opinion this champ is a variation of Shen with little more dmg, though i have to say: At the Moment i fear the dmg of him is too low and hopefully he will be buffed, but we will see...

: Slow down the enemy and reducing his dmg for a short time - great combination with our slow, works well for getting before the enemy to throw him back with our ulti !
: Flash before the enemy, throw him in your team (with ulti), or just to get away with...

- for getting more dmg out of him- Lee Sin depends hard on his spells, so an higher level is a great advantage

- Desolation - We hit physically, that's it
- Armor - Just to get a little more armor against other melee-champs
- AS works fine on Lee for me, the more the better
- AS works fine on Lee for me, the more the better

: for most singletarget-dps
: for greater shield and heal through skills and physical dps
: Only 1 point at the beginning, just for farming and Slow
: His ulti is very nice in teamfights for splitting the enemy team or for seperating one enemy from the others

- works great on Lee, his physical hits do the most dmg combined with his skills
- All Lee needs, more dmg, more speed and slow - perfect item
- Exchangeable with Berserker's, but for getting in and out respectively to catch somebody they are very important..
- lee's passive gives a great amount of attack speed every time it's used, so a little more AS is a great idea combined with Wit's effect cause of the fact that there will be lots of time, where lee hangs on his enemies burning mana
- gives us little more tanky
respectively- depends on what kind of enemies are against u
- Lifesteal and Attack dmg -> NEED !

Pros

• Can get into fights quickly
• and escape from them again...
• Mass-Slow-ability
• Nice Shield (not the highest amount absorbing, but often usable) and Lifesteal with Safeguard
• nice Ulti for seperating enemies respectively killing them

Cons

• A little bit squishy sometimes
• Depends heavily on his Energy-regeneration, which i think is too low ;)
• Depends heavily on his Abilities
• Very vulnerable to magic dmg

helps u a lot with that, combined with
u can kill lots of minios in a short amount of time.
The life-steal and the Attackspeed, granted through your passive, give u the ability to kill minions very fast

As I mentioned, actually i see him as a sort of Shen with more dmg
He has nice support abilities,
can heal himself through lifesteal and spellvamp,
can shield an support allies and can slow and burst enemies

My build is the combination of SupportTank and dps, with focus on SupportTank

I tried him in jungle too, the result was:
GREAT!
but I prefer the non-jungle-version of champs so my build don't get the jungle build

For jungling i took:

as my first item, standard procedure:

Armor + 5 *
Summoner Spells: Smite + Flash

I'm sure he can be played without Smite, but i don't have realized how yet, some change in the runebuild respectively mastery will do this possible I think.
