Even with champions like Susan or Cho'gath, who don't have much in the way of lane presence in the earliest of levels against top lane melees, I don't really struggle against Darius. His damage output has been neutered, he can't really recover with all-ins if the other guy snowballs (unless facing squishies or wet noodles like I Am Oak, Rumble or Mundo) nor can he cope with jungle pressure once his Flash is out of the picture. He's a sitting duck from that point onwards, on top of his late game not being anything to write home about if he can't establish an advantage in lane. Alternatively: even if you do play it safe and feel a tad bit anxious duking it out with him, you can still outscale him for teamfights with actual utility since Darius gets kited all day and doesn't benefit his team if he's not hitting anyone.
