I'll get onto making the lifesteal and so forth in my build(s), thanks for the advice and the +1

i see some nice improvements there ^^ i'd still say he doesn't need health if you give him enough lifesteal (which is 25% in both our builds) but perhaps it might indeed come in handy early game as my build requires some more escaping skills :p
I suggest you get the lifesteal part of bloodthirster earlier to increase survivability.
Other then that its pretty usefull build for new players to start with as it requires less skill to stay alive. You earned a +1 from me now ^^

but something like Zeke's Harbinger

Just got a 32/4 and won us the game, the atk spd on this build allows you to kill and push towers so easy, you just need to watch the damage coming at you since your such a glass cannon

@Janitsu
Yeah it's more of a glass cannon type of build, i may switch one of the phantom dancers to a health item, i just put that update in my 'Items' Section which explains that if you are finding trouble get a health item due to being so low on health.

Good build, high attack speed and damage. But only thing is that in my lane was 2 champs and when i killed those i needed to recall because my health almost over. But still a good guide!

@TheOneWithBrains
The frozen mallet was there not for the slow, but for the health and the small atk boost, the slow is just an extra bonus, its basically just for the survival so you can multi kill with it, also i looked at your build, its nice, yet to try it but will soon, i am going to move some of the items around, namely the 2 Phantom Dancers because i think he needs more attack at the beggining as well, i really depend on my wuju style to maintain my atk until i get my infinity edge.

Also thanks for feedback i really apreciate it ^^

ps i made my own yi build aswell, you might want to take a look at it for more info ^^

its a decent build but i would skip the mana and health boosts to exchange them for more attack speed and damage. More damage gives an andvantage as it stacks up with your wuju style to have very nice attack damage early game while attack speed helps with hitting faster making your lifesteal work faster aswell (more hits to steal from). Cooldowns are ok, i never need them to be lower due to his ulti effect to reset all cooldowns but it might be helpfull for others. Frozen mallet is kinda overkill as you already are one of the fastest champs around especially with ulti and 2 phantom dancers so i would change it into something to prevent stuns, snares ect. as yi is a squishy champion and needs to be able to escape fast.

To conclude this i'd say its not bad but it can use some improvement before i give you a +1 ^^
