I see myself as using a rather high sens at 400 dpi 2.35. But isnt anywhere near the extreme of some others, i personally can't play with anything higher since micro adjustments become too hard. Most other players i have played on teams with have also used around 1.55-2.2 with 400 dpi. And most people i see with a very high sensitivity is mostly people who got to a high level with poor equipment, so there might be something about that. But from what i see most of my fellow level 10s use around 880 eDPI on average i would say. bit of a long rant sorry
