How do you build against true damage
When they also get Blade of the Ruined King? You are screwed from either side... This is what happens with Yi. No one likes to admit that the damage that champ puts out is pretty insane. If you CC him and can burst him down in one go your good. If you don't he will alpha strike skill shots back to back meanwhile dealing A LOT of damage to your whole team... even if you are a tank. I have never liked this champion.
is a very useful item against Yi. As is
.

So even if you have one champ to CC him you need 2 now.
is what some people would say like it mattered and get downvoted.
