A lot of my friends have high sens. I used to play Val using 1100dpi and 0.8 and the reason is that at that time I don't like to move my arm that much so I just used my wrist. Until the moment that my wrist started to hurt so I change it to 0.3
You are either kovaaks nova/astra or at least gm and radiant in val or you are hardstuck bronze 2 who will never get out because ur mouse control skills are way too bad to be able to handle ur sens.
