Yeah, I meant that I encounter some players that I "can't hit" also, but that's just because they have really fast reflexes and gets me a hs or two before I even get my first shot. In ET like El! said first hits are really important. I can feel your frustration, we all were and will always be in that point vs some players. 😄
About configs I must say that my acc got up from ~40 to ~50 with a good config (and lots of hours playing ofc :D).
