are you saying you are killing enemies very fast with you QOS off or on?? Also, what game are you playing? on COD I actually have better games with my QOS off but thats because my speeds are high. I have fiber and if I turn my QOS off I get better bufferbloats because I'm getting full speeds which is making my ping lower...if I turn QOS on I get way lower speed readings and a lower bufferbloat score....which to be honest I dont even trust bufferbloat readings anymore.
