question about builds....
irelia got a little ahead of me and I couldn't 1v1 her anyone....do you guys think blood thirstier woulda been a better choice instead of last whsiper? they were stacking armor
or infinite edge better? i already had some crit, and more true damage.
how about static/pd?
i wana know what woulda been more effective against irelia specifically.
I personally think you'd be better off not taking feast, butcher or fleet of foot masteries instead getting unyielding, veteran scar's and juggernaut. Yi's ult already gives him enough movement speed tbh, feast is under powered imo and butcher shouldn't be needed unless you aren't good at last hitting minions in which case you should practice last hitting minions. Especially with an attack speed focused champ it should be easy to last hit.
Irelia got a thornmail which just makes it so much harder for attack speed champions as Yi. Idk how you played that game but i woulda just hugged tower and farmed till i got ganks or till lane phase over and would have tried to get fed else where. Youumos and Last Whisper means you will deal more damage to her fast but also you will take that 30% damage, fast. Again, idk how you played but Yi has some cool tricks, his Q can help you escape, and evade an enemy spell/turret shot, also his W can help you not just heal but take a lot less damage from both enemy turrets and from an enemy attack.
Bloodthirster would have been a better choice than last whisperer if she already had that thornmail or you knew thats what she was most likely going for because it woulda gave you good AD which works well with Yi and the LS woulda helped you not lose so much hp from her thornmail. Again Bloodthirster over IE if she had or was getting thornmail because IE woulda just helped you die faster.
Irelia is a bully champ and that was a tough match up for you, no worries. Learn, move on.
Personally, I wouldn't play Yi top due to the sheer number of off-tank and tank top laners currently in the meta. Yi is still an amazingly strong jungler with devourer. If you can, I'd look up Cowsep on Twitch. He plays a LOT of Yi jungle, and his build is close to what yours is. I use his, and personally I learned a lot from watching him.
i'd have opted for a randuins + hex drinker to give you a bit more durability over the lw + vamp sceptre
Irelia built to counter you with 
and 
. You would have benefited a lot from more life steal and armor penetration. The 
is good for melting health and using your passive and true damage, but 
and 
would have helped to break through her armor and heal back the health lost from . Another thing that would have helped is magic resist.
Also, Yi can benefit a lot from some defensive items, especially if you're behind.
if you're getting locked down
if you're getting killed quickly by magic damage
against AD, also the active is great to use after your Q
against AP, plus it increases your own heal
Build according to what you need

As a main build, interchange one or two if you need to
Never build glass on Yi in general, but especially do not build glass against Irelia. I don't care how fed you are, a Thornmail Irelia will rip through anyone that doesn't have defensive items that include armor and HP in the duration of 1 stun.
With your total gold of 12.8k I would've gotten 
. That wouldn't have let you 1v1 Irelia in an autoattack slapfest to the death, but you would have not died against her and could kill people in teamfights easily. You NEEDED that Randuins.
