His scalings are too high. If executed perfectly, he deals nearly 400% of his AD in one combo, without even factoring in the actual damage of his spells. And then he still has the ability to continue fighting because he gains the passive attack speed, in addition to a rather high base. A build of Bork, Rav, Black Cleaver, and possibly BT, gives him the ability 1v2 simply because he deletes one of his foes and then has the dueling potential to scrap with the other. I would either reduce the scaling on his ult to 100% AD, or switch some of his scalings to bonus AD, rather than total. Remember, high AP scalings are in the game because you can regulate them with cooldowns. But high AD scalings are tougher to regulate because even if the spell is down, you've still built enough AD that your autos will pack a big punch. This is counteracted by him being melee, but he still gains sticking power from Bork, and from the fact that he has two gap closing spells that both actually have relatively low cooldowns. And one of them even gives him movement speed. There's a reason everyone hates Master Yi.
