I'd like to get a muscle memory training put into the game. It'd be a large box room with white boxes on the floor indicating the range. There would be a shape like this on the wall infront of the player:

Basically the player aims at the middle, then sweeps their mouse to any of the color coded ranges, to practice aiming. Making the aiming "Muscle memory"

It's REALLY useful, it helped me a lot in CS:S
