Darius is unhealthy for the game in his current state.

He loses lane to almost no meta top laner. If he goes even in lane he is more powerful than most top laners do when they're 10/0. He builds about 4k HP, 200 MR and Armor He does over 200 damage per hit He does over 1000 true damage with one button He has over 500 constant movement speed with common builds He heals more HP with 1 Q than squishes have.

Overall, he deals more damage than most carries, and he is tankier than most bruisers. This is not a healthy balance. Add to that that he can do 1000 true damage to all enemies after just killing 1, and he by far outdamages even the best hypercarries in teamfights.

It is obvious that he is getting the Lee SIn and Zed treatment; not being nerfed because people love to play him and see dunks. But it's so painfully obvious that he outclasses any other similar champions. He is reliable, not needing gold to be effective, he is safe, building full tank, and he has higher reward than most high risk champions.

Darius is not healthy for the game in his current, hyper-carry state. This is evidenced by the fact that he has one of the highest play rates and win rates, with a 55% win rate AND CLIMBING in diamond with one of the highest play rates.

I am a Darius main myself, and it's just laughable to play the game with him. I almost feel like I can't lose lane, and if I do, I tell myself "I'll just pick up a triple in the next teamfight by pressing R." and I do. He is fun to play, but that should be no reason not to nerf him.
