Master Yi champion help

Hello, I would like everyone's advice on Master Yi whoever uses him and is really good at using him. I would like to know what kind of items/runes/spells are perfect for Master Yi when playing at Summoner's Rift, Twisted Treeline, Howling Abyss and Crystal Scar. I have my own that I use for Master Yi on each map, but I want a more expert advice on it. Which 7 items would you recommend for Master Yi for each map if its not on here or if i'm not using it already.
Here is what is use for each map. If you have better items/runes/spells for Master Yi who really knows how to use him well, please tell me.
-also I haven't put any runes on Master Yi yet cause I don't know which one is perfect for him. -The items in bold are the 7 item slots that I regularly choose out of all the items for each map for each game.
For Summoner's Rift and Twisted Treeline I use the same items. Starters Boots of Speed Doran's Blade
Essentials Berserker's Greaves Avarice Blade Grez's Spectral Lantern
Offense Youmuu's Ghostblade Lord Van Damm's Pillager Phantom Dancer Wicked Hatcher
Defense Dervish Blade Maw of Malmortius
For Howling Abyss Starters Boots of Speed Health Potion Mana Potion Doran's Shield Doran's Blade
Essentials Berserker's Greaves Infinity Edge Statikk Shiv
Offense Last Whisperer Youmuu's Ghostblade Ravenous Hydra
Defense Guardian Angel Mercurial Scimitar
For Crystal Scar Map Starters Boots of Speed Prospector's Blade Health Potion
Essentials Berserker's Greaves The Brutalizer Blade of the Ruined King
Offense Youmuu's Ghostblade Lord Van Damm's Pillager Phantom Dancer Wicked Hatchet
Defense Dervish Blade Guardian Angel
because his main form of damage is auto attacks. Next I get
for both the active and sustain in the jungle. Then I grab
, I put off upgrading my boots till after finishing my
so I know if I need
or if I can build
. This is Master Yi's core build. build these items every game you play him in the jungle. Next up is
for the active. Use this and R (plus runes and masteries) to hit the 2.5 attack speed cap. This is all the attack speed items you will need. Normally, I'd say build crit after that, but because of the
on-hit yi is just so much better than crit yi right now. So, up next is either you build
and 1 defensive item, or
and 1 defensive item. If I'm really ahead I build both BC and BT for funsies.
. He has equal lategame damage scaleing to you and you don't have enough burst to kill him before he can ult, his ult lasts longer than your w, so it makes it easy for him to dual you. in this case, win the 4v5 teamfight, and you can push faster than he can because of your passive. He can't crit towers so you kill them faster with attack speed.
