Well, I have to say, due to the recent Lee Sin nerfs, he's not as OP anymore, (but he's still super top-tier), and his early game has been toned down a bit. However, you are not weak.
Really, early game, you just want to jungle peacefully. Acquire or give out buffs as needed, and cover or gank lanes. Once you get Wriggle's Lantern, Mercury's Treads, and maybe a Phage, you will start to dominate harder and harder.
I think, and perhaps it's just how I play him, Lee Sin is very strong all game.
His early game ganks are very scary, he's crazily mobile, and his mid - late game damage is stil very dangerous. I think that the most important thing about playing Lee is having a strong start. You don't want to get shut down, or you will be a lot less useful as you should be.
How do I do this?
Well, first of all, it's very helpful to have contact with your teammates, either through Skype, vent, or whatever else. If you can communicate with your team, you will have a lot easier time doing your job. It's a lot easier to land Sonic wave and position yourself for a good Dragon's Rage if your teammates actually help and time things properly. Try to also gank the lanes that need the most help, or maybe a lane that is over-extending and pushing too hard, than ganking a lane that your team already dominates.
It's hard to keep your eyes on every part of your map, so that's why I enourage you to play with people you have communication with.
Of course, that doesn't mean you can't carry solo queue like a boss, I'm just offering some help to newer players.
Remember this: Sneaking around and snatching up kills is not what you do. It helps, but that's not the point of Lee Sin. You need to HELP and SUPPORT your team, and that means covering a lane, or feeding lots of kills to your carry, and not yourself.
Second of all, you need to keep a close eye on your jungle. In early levels, strong counter junglers like Shaco and Nunu can really mess you up, especially by things such as taking the golems you need to complete your first route, or ganking you as you take a buff, taking both the buff and ambushing you, either forcing you to recall or be killed.
If you have a good team composition, in this case, a support with Clairvoyance, it can help you a lot. The support can effectively use Clairvoyance to spot the enemy jungler so you and your team can spot ganks, jungle invasions, or suprise jungle ambushes.
Refer to "Annoying junglers who may be a threat" for more info :P
OKAY, so, yes. Dorans lee is very strong, especially early on in the game. With these runes, you have around... I think 90 AD at level 2, so when you gank either mid or bot, you will completely dominate. Wriggles is still pretty key on lee, and as you can see, I took an early trinity and then atmas. If there's just too much magic damage, considering rushing a Negatron Cloak somewhere between Wriggles and trinty.
Here's how the route goes:
-Wraiths (save smite) - You should not get a leash and have creeps running everywhere. Hit it and let your teammate do some damage. As long as you get the last hit, you get the exp, so dont worry.
-Red (Now this time get a proper leash)
-Go gank! - Yes, you dont have tempest/cripple, but that's okay, because with 90 AD and red buff, as long as you can land your Q and have your teammates follow up, there should be a kill for sure.
- clear the rest - Either take blue or give your team an early blue.
Remember, this build focuses on lots of ganking and getting fed off kills, so be sure to gank instead of just trying to farm in the jungle, as he is no longer one of the fastest junglers.
*IF YOU HAVE LIFESTEAL QUINTS, THOSE WORK TOO. MOBAFIRE WAS BEING ******ED AND I COULDNT FIND THEM SOOOOO.....*
A bunch of people said that they couldnt make it past golems, and well, it is kinda hard if you dont have the runes, but hey, heres a video anyways. (i made it in 10 minutes, dont blame me for bad quality :I)
NEW JUNGLE MAKES ME MAD GRRRRR
Okay okay by request I have changed this part. I tried to new route and it works, so here ya go.
Start at wolves. Tempest, and remember to use your passive. Don't use cripple until you've dealt the 2 hits from your passive. Then use cripple. Save smite. Go to the wraiths. Smite the big wraith. You should level up after you kill it. Get safeguard immediately and cast it on yourself. Again, utilize your passive and finish the wraiths. Go to the double golumns. Because of the new route, you will not have smite up for these. But it's okay, you're lee sin and you should finish them with very low health. Remember to cast safeguard upon urself or you will die. then recall. You should be level 3 by now. If you think that you will be underlevel, you wont. When you go back, if you did it correctly, you should be level 3 while the other lanes are only level 2. After going back to the jungle, go to wolves again, save smite. Then, if there is a teammate who needs blue, ex: Swain, Lux, Brand, etc., get it for them. If not, you can get it for yourself. Proceed to get red and go gank! :)
This does not mean that you can't gank before this, but that is something I cannot teach you. But theoretically, you can go and start ganking by level 3. I just like to get the buffs first; it's personally opinion I suppose.
- DONT GO BACK BECAZ NO GOLD AND ****. GANK INSTEAD.
-Wraiths(if you dont gank)
-Golumns (if you don't gank)
cover and gank and **** accordingly.
