How am I wrong? I literally just described your whole trailer.

It's was only one kill in the trailer where the enemy was distracted What are u talking about? Watch again Everyone else I killed was trying to kill me

It happened more than once. In many situations they started shooting at you and then your teammates ran by and they got distracted, letting your abysmal aim with the last word finally get you the kill. In other situations it actually surprised me how bad the people you were playing against were. You missed so many shots and were still somehow able to get the kill. All that your trailer showed was that you have poor accuracy with your guns and are struggling to get half decent clips together.
