Game update and Beta version

Why was the game update rolled back and the features presented in the beta version were discarded after the first week? You guys promised us an improved passing system that was kept for a week and then we returned to the previous system. Why was that? It's not the first time it's being done. Every six months you come with a beta version that promises us an improvement in the gameplay but somehow everything you forget to bring those changes into the actual gameplay. It's like you guys don't want to improve. I thing the latest beta gameplay was decent if not actually good. What made you change?
