Problem with Thorn is that the DoT starts to chew through players after 3 body shots to the point where it can kill you, so it doesn't encourage precision shooting for a Handcannon. People also enjoy running after landing 3 shots, which again is not okay, because they know they will kill the person from the DoT. All of that combined with a heavily distorted view when afflicted by Thorn doesn't help, the screen becoming filled with unnecessary mass afflicting the screen can throw off depth perception.
