I honestly don't get all the fuss about Cho'gath, he is completely immobile minus Flash (Righteous Glory isn't even that good anymore compared to what it used to be), Q is super dodgeable and you have to be a moron to hit it. Yeah he can kill somebody instantly with ult, but he is useless besides that, meanwhile Darius proceeds to do that to your entire team if he lands 1 killing blow, hell any ADC late game will delete people much more efficiently than Cho'gath's combo that requires 2 items + 5 min CD summoner to be reliably pulled off, meanwhile ADCs with automatic AA turned on or attack move don't even need to click on their targets.
