First off that has nothing to do with what I said. Nasus is not a Tank, and that puts his kit in a very different light. Juggernaut is a subclass of Fighter, and their entire goal is to deal damage. You at least need to get the classes right when talking about champion balance, because if you balanced Nasus like a Tank instead of a type of Fighter he would need massive buffs to his utility.
With that out of the way when Kleptomancy was nerfed his win rate dropped like a rock. He now has two keystones at 50% win rates, and everything else is below 50%. Simply saying he is broken is not the end. If you want to make that claim you have to show why he is broken with such a pathetic win rate. You can't just say something and expect people to side with you, you need to provide an argument that challenges what people think. Baseless QQ gets you nowhere.
