Wont work no ****ing deffence

This is totally best and OP build!, let me tell ya my last game with this build:
Stats were 27-3-0
So, i went to 3on3 with my 2 friends, they was at LAN and internet went VERY laggy, so they left game and i keeped it 1v3. I won it, how? They all attacked me at same (1v3) i PWNED them all like 2-4hit, they was like CHEATER!!!!! and i got triple kill at their market turret without dying!?!!? i 5 hitted turrets LOL! and nexus too... This build is so OP! I LOVE YOU!

Hah. If you get fed, you have 4 levels above others . . . you can usually 2 hit or 3 hit the tank and your team is also a few levels above, so yes wow 2 second difference won't make a caster get the whole team, you can take the caster if you want I never said follow the build 100% get inspired.

Focus tank? Wtf? No. Yi does not focus tank. Yi destroys the opponent casters before they can kill the rest of your team. If you attack their tanks, you are only helping them. -1.

I'm Not so sure lol'z I can rack up a good 10/1 ratio on good games with this build so anyhow i get my items really quick. On Bad Games i usually do 1/1 or 2/1/1 as a ratio not total of course ^^. I get Sword of the occult because it is so easy to stack on it, after a few minutes of gaming after getting it you already have 5 or more stacks, 5x5 = 25 Damage+10 Base damage, at lvl 10 or so that isn't bad with stark's lifesteal.

Anyway if anyone can try my build out apart from me and tell me if it works i would really be happy ^^

I agree that with you about the greaves, I got a Guide to Yi on my profile, and its all about synergy. Different Boots for different situations and builds.

Ive also noticed that you build Starks first, which is great to get early, but you need more dmg to make that lifesteal effective. You might get enough LS to last long enough to get a few extra hits, but you dont do enough dmg to make it useful. Get a long sword to go with it. Will get better results

Thanks, I Would Rather Take The Greaves, because 25% Attack speed isn't negligible

Otherwise Thanks for your comment.

Change the Greaves to Tabi and you be ok. I say that because you have Dodge Seals and Phantom Dancer. Stack the dodge, just my opinion. Other than that GJ
