Darius Is Not OP
Darius + Q = 36% heal
Very fair, I remember a time when Darius could be killed in battle. Those times on the rift are finally ceased. I'm tired of seeing my old friend die on the rift. I am very happy Riot implemented a technique where, Darius, can get a little of his health back. He only heals a little bit and doesn't change fights at all. Plus when he get's 5 stacks of hemorrhage on you.. eh it does a little damage when he ults. But not something you can't flash right? It's a skill shot that can be dodged. Anyway When he 1v1's he only heals 12%+ whatever healing you have. So I mean blah blah blah, he's an alright champ. Not the best, but whatever. He can easily be 1v1'd by Batman, or Naruto, so It's not that big of deal.
Darius Healing = basically nothing Darius Damage = Not Noticeable Darius ability to Carry a Team = Non Existent
Just dodge his Q, and don't get auto attacked, you'll be fine. Also whatever don't get pulled, but that can be flashed too :D
Keep Darius the way he is :D
