I first time karthus in ranked and I'm at 2-0 in silver but I honestly have terrible camera and mouse control and just got hard carried both games. I know it's really personal preference, but I was wondering what settings you have to have more precise mechanics. I find it extremely difficult to kite back while Qing and weaving in autos. I'm using 2000DPI with 50 sensitivity for mouse and 40 for camera movement. I do have a "sniper" button on my mouse so I thought maybe I could make use of that. Any tips?
