Juggernauts are Overpowered

Juggernauts, they don't have to build any damage item, yet can smash an entire team single-handedly. Yes, they have "counterplay" but that doesn't matter when you have a Darius who flashes over a wall and pulls your carry for an insta-kill. A champion shouldn't be able to take tons of damage while also dishing out more than a carry. Its unbalanced and out-classes all other roles in their respective lanes. Every game, I see a juggernaut, and that juggernaut more often than not will end up carrying. It makes the game boring and they need to get nerfed.
