The difference between good and bad Darius players.
The Bad ones want to snowball so badly that they want to attack you any moment they get and just want kills so much it's both pathetic and annoying.
The good ones are strategic and patient and wait for people to screw up, because they know they don't have range and they are not immortal.
The fun part is that the bad ones always end up feeding while the good ones obviously are dunkmasters. Anyways I am just talking from experience.
