I'd really like to see in the future the removal of the colored smoke indicating a fire support mission has been called in. First reason is its obvious and gives plenty of time for the enemy to evacuate the area. Second its not realistic, alerting the enemy to your intentions with colorful smoke isn't normal.
I also think the sprint speed is too fast. If it were to be dialed back some to prevent people from just zipping all around the map. It prevents the game play from being immersive when you should be taking your time to check corners and scan sectors.Slow is smooth, smooth is fast. The gameplay seems faced past because of it.
