Well Spasm, everyone isn't as good as you are, especially me, so to try to shoot the Scout from the hip is not gonna happen and I'm pretty sure that I'm not the entire minority, same goes for the AWP although I have gotten many kills close w/o opening up scope.
I'm sure that everyone has there own little ways of dealing with different guns, but my statement was simply a generalized one that would pertain to the majority and not the top players of GG
