I was really bad at PvP. Blue weapons, getting blink shotgunned and sniped every life. I had a .4 kd Slowly, I got better to the point I had a 1.4 You get better playing people with good connections that are all over the spectrum (mostly better) than by playing similar players with lag. The only thing stopping you from improving is yourself with cbmm, as lag is much much less frequent. CBMM also makes playing with friends much more fun.
