I was just playing a few minutes ago and when i was looting an apartment complex, i started thinking of what would happen in a firefight in that building. then instantly i thought about blind firing. i was thinking maybe like just hiting a key and you could move your weapon to the right, left and up to shoot around obstacles more easily instead of peaking your very vulnerable head out just to get shot. also maybe your weapon could get shot by and enemy while you are blind firing it and then it gets damaged and maybe even disabled. i really think this would be a great add on to make fire fights and other encounters more interesting.
