Good points, majority I agree with... Sorry for my inactivity lately I've been on vacation like Taint mentioned and then missing my flight home delayed me further..
Anyways I don't have any issues with the hitboxes but it appears others do, this could be due to them playing at another server alongside FG and since we use different hitbox type instead of a cylinder/box we make it possible for pellets to go under/over/inbetween body parts making damage/spread an either more RNG base, plus our hitbox scale is smaller than another server therefore aiming needs to be more precise.
