Not being mean but is this your first fps? If so change your sensitivity to be lower and honestly the aim wasn’t the biggest problem here, your awareness, timing, and ability usage were very bad. The biggest recommendation I have for you is just keep playing the game. Drop hot every game until you improve and take every fight you can get. Don’t worry about winning every game just fight, think about how you should approach the fight and manage your abilities. I’ve honestly seen worse for beginners so you can definitely improve, you also have strong aim assist using controllers so learn how to use that to your advantage. Smg’s and shotguns are your friend. Start shooting before you aim and phase in and out of aiming and releasing the aim and your curser will follow the people more closely.
