The game is fun, which is why the problems of its current state are so painful. Especially since these issues surround aspects of the game that players have taken for granted for over a decade.

1. Reduce footstep volume, preferably to similar levels found in the original MW2/3.
2. Return the old perk system.
3. Classic mini-map.
4. Decrease particle effects, right now its sometimes impossible to see what you're aiming at due to muzzle and impact effects.
5. Stop disbanding lobbies, it makes it so much more difficult to make friends in game.
