I was wrong when I said "Is happening all the time", was just an expression. I took all kills with 2 shots, but sometimes, my second shot doesn't give dmg to the enemy. I will repeat again, they don't use KI3, the distance is under 90m, is happening at 20m too, I shoot quick, I don't miss the bullet :)) and this was happening to other players too.
Merged.
I will really appreciate if people stop give me "confused" and they will come with arguments that help me to improve the problems of my posts...
