Because of this: Map is Pantheon, character "a" is at A spawn. Character "b" is at C spawn. They both go to the long corridor back by the waterfall and stay at their respective ends of the corridor. (We will just say they have their backs to the wall on each end for clarification.) "A" is using Thorn and is able to two shot "B" from this distance, dealing very near full damage. "B" is using Vision of Confluence and is hitting for around 65 damage per critical, albeit at a slower fire rate. Unless you get the drop on a Thorn user, you will very likely just trade kills with them or die outright because he launches 2-3 shots at you and then runs to cover. Aside from the poison, The Last Word and Hawkmoon and basically any other hand cannon deal more damage at the same range, therefore making scout rifles [i]obselete[/i] if you want to get technical.
