Treyarch has a hardon for adding unnecessary stuff that will ruin gameplay. It's was proven in the past that full-auto version of semi-auto guns were overpowered, but they still add it. They tell us they want to make a game that makes camping harder and then give a attachment and a portable head glitch shield that makes it easier. And then the stuff that was already in previous game they ruin. I hope that the next CoD is more focused on game performance than focusing on unnecessary stuff.
