I was a 375 armour chogath with 4500 hp and he could kill me 1 v 1 in like 5 seconds. Its so unfair, he was tanky ish because of blood thirster, GA, phantom, and frozen mallet.
While it's true that Yasuo is bullshit I'm sad to tell you that Cho is right now a terrible tank. Best results achieved playing him as a full AP mage or an AP bruiser and hoping for buffs.
The changes to W were a straight up nerf. Cho used to be pretty great vs Yas early game, and not he's downright terrible.
Cho Gath will lose to any AD & AS based champions, His pretty much a gigantic walking meat who is waiting to be cut down.
HEY! THIS 
! Buy it! 10% damage reduction that Yasuo will have to fuck up his build to avoid.
