I'm not going to explain the reason of this items or any that ****, i think you all guys know, i think you guys just wanna know how to win, man it's a rly hard question, im gonna tell you what i do when i play Lee Sin. Normally i start at Blue, it's the same thing, but in blue i can steal ther red or wait for the enemy jungler and try to draw the first blood, depends of the enemy jungler must be a squishy enemy jungler for the first blood, for me Lee Sin can counter any ****ing jungler you just have to know how to mange him, you have to know how to master him, it will take some time, but that's with all champions, always take time to manage something, in game, you must counter jungler every time you can, you must gank hard you can in early game, early game must be your's to garant you the win, well, i start at Blue and i finish in bottom lane Golems, to reach level 3 or 4, then i have all the spells available to gank expect ultimate, but the time will come, when you finish the jungle at bottom lane, start the pro ganks, like a monkey, normally i start gank at top first, then i go on mid and then on bottom lane, you must manage your Q, hard you can, you can't fail it, so basically in early game you must gank was hard you can. In late game i advice you to split push a bit, destroy some turrets and get a decent farm, but dont miss all team fight's, in team fight's you must flash to ad carry back, and kick him(ultimate) to your team, i advice your teammates to pick a ad carry or something with stun, like Ashe, then you can kick(ultimate) the enemy ad carry to your team and then they can stun him and kill him instantly, well guys, just do your best, and dont flame your teammates play chilled, good luck guys and i hope you guys like my Guide/Build. Sorry for any fail in my english guys.
