Darius

He's one of the most kitable champions in the game. He can do well against some melee during lane, but he can't do much of anything against ranged champions, which pretty much flood top lane in the current meta. Also worth mentioning: His base stats aren't notable in any regard and he's the only bruiser without some form of innate tankiness or sustain.

Basically, he isn't played competitively because he's terribly weak as a champion.

So if I used a ranged champ like teemo then i'm fine?
