Not really, I've been seeing tons of Darius's lately I've been pretty easily shutting them down. Vi's E, Olaf's Q, Charging him pre 6 as Jax to force him outta lane, etc.
Darius actually does very little damage compared to other champs and only has a pull and sticking power. He also "caps out" early and has a meh late game upposed to champs like Jax or Olaf.
Granted I'm not neck deep in Ranked or high Elo but by the looks of things Darius isin't that godlike. Kinda wanting a Darius freeweek so people get plenty of practice against him or walk a mile in his shoes.
In short, he ain't OP, and this commin' from a scrub like me.
