I was on a competitive team in Battlefield 4 when the game came out, I know the game isn't like the competitive scene in CS:GO but I put so many hours into playing with my team. Learn the callouts and after a while, I just called them without thinking twice and most of the time it came out smoothly. When I would stutter, they wouldn't mind as much but usually my adrenaline is running and I'm focusing on the win and those key kills.
