Your game is full of not working hitboxes.. If you wanna grow, please fix that shitty hitboxes, thank you. I have lot of hours on FPS games, CSGO is one of them and even this game have better hitboxes.
I know what you mean you stay very close to the enemy you see him first you aim him but the bullets didnt want hit , this is so dumb sometimes. The enemy hits you with a pistol from the other side with a headshot and you hit only his legs or chest.
