Dont Let Yasuo Farm
First of all this guy can probably win his lane, but if he doesnt, DO NOT Let this guy farm. I dont care what people say, he is broken as hell.
He only needs 1 item to match the damage of someone with 1.5 items.
He usually gets static shiv, or phanton dancer and can farm super easily, just take out waves with one Q. This guy turns into a monster. If you have an advantage over him, keep it going, you cant afford to go to other lanes and let him farm for too long. Make sure u also ward up incase the enemy jungler comes to help him, but man, do not let this guy farm.
Then a farmed
