The Perfect Teamp Comp by Operator Tom. If you have any questions feel free to post them in the comments. This is completely serious and do not scoff at this till you have tried it. Please also remember that this is a redefining guide on how to play your characters differently.

So you may have notices (or maybe not noticed) that I have built AP on lee sin, the blind support. And you might be like WTFOMGBBQ?!?!?!?!?!one?! Well if you think about it everyone of lee sin's skills are beautiful support skills from his cleverly designed in your face Q to his epic slow of slowingness E then his HOLY **** YOU JUST SHIELDED FOR 600 DAMAGE w. Then you can never forget his R. His R is truly what makes him one of the best supports and disrupters in the game, because not only does it knock back an opponent, but if you hit any opponent with the opponent you kicked, it knows them up as well!

So lets go over the basics:

Skills

Q - Sonic Wave/Resonating Strike: This skill will allow you to harass with extreme accuracy and then when you're ready to initiate it will allow for the in-yo-face style play which all supports SHOULD be doing.
W - Safeguard/Iron Will: His W allows him to teleport between your enemies and your teammates it also provides a shield which gives around 500 damage prevention at level 18. His secondary W is worthless except for getting a second sheen proc.
E - Tempest/Cripple: Not only is this good for finding Twitch's and Evelynn's, but it also slows any champion you want (Except Yi, dumb alien ninja). Also allows for the in-yo-face playstyle. It works extremely well with his R, because you can slow people get in the right positioning then kick your opponents to other teammates or into other enemies to knock them up in team fights (or even away from dying teammates if needed).
R - Chuck Norris - This allows you to roundhouse kick anybody anywhere. That is all.

OK! Now we're onto item choices.

Items

Now, if you notice you don't get straight up AP items, because then you'd be straight up trollin'.
Gunblade - So you mix together some AD as well for his Q and E skills. We got you a gunblade, not because you could use the life steal, but much more because you could use the activated. The key to being a good support is the acivated
you might be able to q to an opponent but whats the good if others can't catch up, so you throw down an E you say, and that might not be enough so then you gunblade them allowing for an extra slow and some damage.
Tri-Force - You're main damage source here, you get a little bit of everything here, some AD, some AP, the Sheen Proc, the Attack Speed, the movement speed and the health. Like I said before, the most important part of the build is the Sheen, you're abilities are so spam-able its not even funny. In addition to the sheen proc you get the Phage proc of potential ADDITIONAL slow. So now you have like a triple slow, so super kiting abilities away!
Boots of Cooldown! - I refuse to type out that long name of rediculousity. SO! Obviously, boots for extra spammage.
Rabbabababadude's Deathcap - For MUCHO AP! But no really, this gives your W the extra oompf it needs to even concider going AP.
Nashor's Tooth - For attack speed, CDR and AP, it has a little bit of everything which is what you need.
Moonflair Spellblade - OK So, Tom. Lets get really, I'm throwing you a bone with even looking at this build, but why this item? There are plenty of better items if your gunna do AP. Well, my response is this. Tenacity. It has it, you need to get out when you need to get out.

Summoner Spells

Rally - As you can see... We got rally Rally is rally is rally is rally. It has no real use UNLESS
you get the mastery for it, by getting the mastery it stays in play longer and gives AP in addition to the original AD, which boosts your power both ways in addition to /SUPPORTING/ the carries.
Exhaust - Extra slow and AD REDUCTION! Keep that in mind. Save THAT for the enemies AD carries. It makes them super weak.
