Is AP Master Yi better than AD Master Yi?
In our Season 3 damage simulator AP Master Yi does 1,323 combo-plus-autos damage at level 18 against 1900 HP / 75 armour / 50 MR, which is -14% versus AD Master Yi, with 3,687 effective HP (-21%). That is a damage comparison, not a verdict: The moment anyone builds health or a Negatron. Crit Yi kills tanks; AP Yi cannot, and a fight he does not end in five seconds is a fight he loses.
When should I play AP Master Yi?
In a snowballing game against squishy teams. One Alpha Strike into a Lich Bane auto genuinely does delete a mid laner, and the reset means it happens again immediately. Alpha Strike is untargetable while it nukes off AP, and Highlander resets it on every kill, so he blinks through a fight deleting one target per jump.
