I dont care what his win rate is, what his play rate is, what his ban rate is
Chogath will always be one of the most unfun, and completely bullshit, damage-heavy super tanks to ever face. He's an absolutely cancerous champion and has been ever since riot introduced his new E and infinite scaling R.
He takes absolutely zero skill to play. The most mechanically retarded silver player can pick up chogath and duel easily a platinum player playing a bruiser (the silver would only lose at that point by not having the macro, csing, etc. capabilites that the plat player would have).
His E is cancer, the fact that it scales off of R stacks and makes chogath a bruiser-murdering super-tank is one of the dumbest things I have ever had the non-pleasure of witnessing and even playing myself.
Honestly, it's not even the R infinit scale, that is manageable although it can feel bullshitty as a squishy to face when he flash stoneplate chomps, but his E is TRULY what makes him cancerous.
Like I said, I dont care if chogath has a 20% win rate, I will always hate facing that champion. He takes absolutely no skill and mundos his way through other melees with his E.

. Cho is highly item relient and does little to anything on his own other than beat people who try to fight him when they don't have the damage to kill him before reaching below about 400hp in which his ult will kill you early. any type of slow criples him since all of his abilities that actually do damage require him to be in melee range to use and with the majority of champs having some kind of dash/ blink or movespeed burst landing his q in the mid to late game is impossible unless there trying to fight in a choke point. Right now he also seems strong because a lot of lanes are trying to move away from tanks since fighters and assassins are taking over top and jg which tend to lead to teams having really low hp thresh hold, which means cho has an easy time getting stacks.
